Regardless of your current skill level, embracing clean coding practices, establishing maintainable code structures, and effectively managing oneself are crucial for becoming a competitive and sought-after programmer in today's professional industry.
In this guide, we will explore essential coding topics that every proficient programmer should be well-versed in:
- Adhering to programming standards
- Programming design principles, such as:
- Single Responsibility Principle
- Open/Closed Principle
- Liskov Substitution Principle
- Interface Segregation Principle
- Dependency Inversion Principle
- Design patterns, including:
- Creational patterns
- Structural patterns
- Behavioral patterns
- Enhancing code readability through effective naming
- Testing concepts, like:
- End-to-end (E2E) testing
- Unit testing
- Managing time efficiently
- Strategically pacing project development
---
It's important to recognise that everything I present here is just a guideline, not a rule. I call them "sins" but in reality, there's exceptions to everything. I think all of the points mentioned in the video could misused, if you're not careful. I've seen people who over-engineer simple codebases to the point it's unreadable, just to have a fully modular codebase; or obsess over perfectly following standards, even when it becomes incompatible in certain situations; or spending way too much time trying to achieve 100% test coverage, when it added no more benefit to do so.
The best way to interpret this video is to have a little understanding of the topics, and choose the things that you want to learn more about. This is not a doctrine in any way, just some tips to kickstart more knowledge and understanding. Everything mentioned in the video once had a pain point behind it that will have led to its creation, but maybe you don't have these same pain points... yet! Just remember the potential solutions for when you do, or use them as a foundation for your own exploration!

(longer description)
Are you ready to level up your coding skills and avoid the seven deadly sins of programming? In this video, we'll explore common mistakes made by developers and how to fix them, leading to better code quality and more readable code.
Join us as we dive into programming standards and the importance of consistency in file structure, whitespace, and coding philosophies. Learn about SOLID principles, a set of design principles that will help you write maintainable, scalable, reusable, and testable code. We'll also discuss programming design patterns and how they can serve as a universal vocabulary for better understanding your code.
Discover the importance of using descriptive names in your code and explore various testing methods, from end-to-end testing to unit and integration tests. We'll also touch upon time management, emphasizing the need to provide accurate estimates and avoid rushing through projects.
By the end of this video, you'll have the tools and knowledge to create clean, efficient, and human-readable code. As Martin Fowler once said, "Any fool can write code that a computer can understand. Good programmers write code that humans can understand." Let's get started on your journey to becoming a better coder! Don't forget to like, comment, and subscribe for more programming tips.

Hey folks, I just wanted to add a quick few things to make the goal of the video a bit clearer: I present these topics as guidelines, not hard rules. I call them "sins" but in reality, there's exceptions to everything and your situation may not need all the topics covered. I've seen people who over-engineer simple codebases to the point it's unreadable, just to have it fully modular; or obsess over following standards, even when it becomes incompatible in certain situations; or spending way too much time trying to achieve 100% test coverage, when it added no more benefit to do so. The best way to interpret this video is to have a little understanding of the topics, and choose the things that you want to learn more about. The 80/20 rule is usually pretty good to combine with all these points. Everything mentioned in the video once had a pain point behind it that will have led to its creation, but maybe you don't have these same pain points... yet! Just remember the potential solutions for when you do, or use them as a foundation for your own exploration! Hope this clarifies a bit! --- Oh, and thank you so much for all the kind comments! I'm reading every single one with a smile. Your feedback means a lot and I am really excited to get back to creating more videos for you all.

[@Timelog88]

I love this added comment, as after watching the video I was pretty afraid people might fall in the trap of dogmatically following principles like SOLID like they are 10000% must does. However, after being frustrated with engineers creating interfaces for everything, every time, everywhere I had began to do a ton of research, there had to be a better way. And for my sanity I found one. Having always been the type to make things work first, and make things better later, Test Driven Development was an eye opener, and I suddenly began to see you don't need interfaces everywhere, nor do I need to mock everything (yey Sociable Tests!). What I really learned doing TDD is that after you get things to work, and backed by (behavioral) tests, refactoring is fun, and useful patterns and practices come to the surface quickly. I can really suggest to people to learn TDD, even if you don't like it, if only to get more insight in when to apply practices and patterns better and avoid the trap that I like to call "Cargo Cult Programing", applying patterns and practices without considering their usefulness in your specific problem domain. For anyone interested in what testing without mocks looks like, search for James Shore here on KZbin, he has a bunch of great video's explaining it with some fun projects.

[@SaHaRaSquad]

I think "don't follow rules blindly" also deserves a place as advice - understanding why some best practices exist and when they make no sense is important. There are valid exceptions to everything.

[@blackrobot138]

Exactly, without any context these principle, rules or patterns makes no sense. This sometime leads to over-engineered solution which is not that useful for the business.

[@callumbirks]

Definitely. I started work as a software dev about 6 months ago and I'm trying to improve our product by following coding standards and general guidelines from the C++ community. But I don't apply anything until I've researched it enough to understand it myself and explain it to others.

[@asmonull]

Generally agreed, on the other hand - when breaking a "rule" (guideline, established practice) it's best if you know how it works, why it's there and what are the tradeoffs; at which point you probably don't need a guide/video to tell you that.

[@IBelieveInCode]

In fact most of the "good practices" become crap when you have to do something enough complicated for that. That's why I have finally rejected OOP 🙂

[@mrmaniac9905]

I've been programming for 12 years now.. this perfectly articulates what I've been subconsciously been leaning towards as time goes on. I've heard about all of the concepts in this video but never in this way. These principles truly are fundamental measurements of ones proceffiency in code. One thing I will mention though is the concept I personally use with larger programs. When I am facing a large system, I will typically prototype smaller bits of code in a way that "just works." After I get my concept I have in my mind in front of me, I then begin to refactor and abstract the code into a state that is to, in my eyes, what is described in this video. In my game engine I've been working on over the past few years I started off by just getting things going like a window, simple rendering with shaders etc. Eventually over time I separated out the project in modules that hook the engine for state changes. The core engine eventually just became a bootstrapper for modules like an Asset module, and other modules could depend upon modules within their module.lua file (custom build system), and I had I things like abstract modules where a render backend could be opengl or directx, where there would be an abstraction module that provides common rendering functionality, allowing modules that need to render something to just require the abstract render module and let the runtime render module handle the rest. TL;DR sometimes its okay to just "get your idea out" with some working prototype, then chip away/refactor as you would with a beautiful marble sculpture; apply the principles presented in this video as a form a improvement overtime instead of must-have requirements from the get-go. Principles such as standards should always be followed in my opinion however.

[@coderized]

Well said!

[@ErazerPT]

"In most projects, the first system built is barely usable....Hence plan to throw one away; you will, anyhow.". Fred didn't mean it literally, but on a functional level. If you're doing something new, odds are you wont DoItRight straight away, no matter how much analysis you throw at it. So might as well GetItDone, go over it figuring everything that is wrong, then DoItRight, or as close as possible. At this stage in the process, refactoring is counter productive IMHO, as you don't have a "code block level" issue, you have a Systems Architecture issue. Reuse maybe, refactor not so much. Assuming v2 went well, you can now just refactor/rework, and bar some fundamental change, things should sail along quite ok, even if not optimal. Most (legacy) nightmares are from systems that didn't Throw One Away, because (business) reasons. And they carry all that bad SA into the future. At that point, any refactoring/patterning you throw at it is just "reshaping" a fundamentally wrong thing. Funny thing, if/when they do decide to do it anew, they don't use the old one as "reference" and just start working one the new one, with zero intention of throwing the prototype away. Wash, rinse, repeat.

[@jamesgood7894]

Was reading a Haskell book “Abstractions in Context”. The author suggested that if your initial design/interface isn’t perfect, don’t toss out the code when going back to improve it, but to wrap it in an improved interface (kind of like the adapter pattern) in order to provide a better interface to the user/calling code of the module.

[@ErazerPT]

@@jamesgood7894 Haskell has a easier time by dealing with immutables. In languages that deal mostly with "by reference", one of the main reasons you throw out a SA and replace it wholesale is not because of the code per se, but because of the bad side effects. Something that looked like a good idea in the prototype has become a true nightmare, and now you're in lock/mutex/semaphore hell because of it. No amount of refactoring will solve that, you need a new SA that deals with "what will happen and how to avoid it". Problem being, you can only know how big a nightmare it will turn into post facto. At the extreme end, it gets so bad you'd be better off running single threaded because you are waiting on something that is waiting on something that... ;)

[@lovalmidas]

Getting the idea out is perhaps the most important part, perhaps even trumping standards or principles or patterns. There is usually a distance between a blank slate and proof of concept. And within that distance is a graveyard of failed projects. Building that stamina to survive this is perhaps the most important for devs at the beginner level who are still grasping the mindset of programming itself. Have a process. Then improve that process. Just as it is too easy to devolve from developing a game into tweaking the game engine (and fail to produce a game), it is also easy to fall into the maze of standards to the point where the product no longer progresses, but gets stuck in the sea of refactors and compliance checks - a lot of movement of letters without useful function. With experience, both in coding and in procuring programming aids and tools over the years, we'll get better at separating prototypical code from final code, segmenting parts of the product to useful levels of abstraction, when to stop coding and start reviewing and refactoring, and even start to internalize some of the best practices to minimize the effort from prototype to product code. This is the typical audience for this video. Beginners are welcome to see the roadmap of their dev journey.

[@agiliteaV]

I'm new to python and programming as a whole and I am completely lost. All I've done is partially work on a cash register.

[@fabdlnltc]

@Agilitea familiarize with python doing basic algorithms. First learn to speak fluently in this new language. Whatever you want to say, write it in python. All these topics will make sense after you know how to program and try to do it with someone else. The only exception is the topic on learn to properly name your things. That is simple and often ignored (stop naming your variables as a, b and c. Put the name that will make you understand your written code a week after you left it) Revisit this video everytime you think you've made a big step toward programming, because you will understand each time a little bit better and figure it out all topics spoken here, and maybe use it as a starting point for deep learning something later

[@hotworlds]

To expand on the first point, a lot of IDEs have an auto formatter that will fix your whitespace and indentation for you, and can be run on existing files all at once to clean everything up. If you're on a team, it's a good idea to create a configuration for the formatter and share it with everyone on the team so it's impossible for anyone to make formatting mistakes :)

Absolutely true, I forgot to include this point! Tools like "Prettier" and linters with auto-formatters can save you so much time and headache. Thanks for the addition!

[@karoshi2]

Git hooks for the rescue! Although local ones aren't shared and until now I couldn't convince people to have them installed on server side, one can still have a shared hooks project that comes with automatic updates and an installer. Doesn't need to be for style, but syntax at least. Have seen it multiple times: A does a "minute" change that "can't possibly go wrong" and B spends days searching for an issue he never introduced himself. Ok, B might have read the git log, or bisected it, also when A doesn't even check the syntax how likely is it to have him install hooks, but you get the point.

I understand this very high-quality video requires very intense effort and time, but I wish you can make more videos like this. Thank you for sharing the knowledge!

Thank you, this means a lot!

The code I wrote primarily implemented some mathematical calculation. Code and it's documentation are not always well linked. So I made it a habit to describe the derivation, references to text books used and even put Matlab simulation code used directly in the comments so the next person to service the code could see the whole process and repeat it if changes were required. Years later I visited the company and the engineers that maintained my code thanked me.

Amazing video! As a person that usually overthinks problems and suffers from a severe case of impostor's syndrome, this video is a breath of fresh air. It's clear, concise and gets to the point - exactly what I needed! Also, the production quality of this video is just stellar! Do you use After Effects? Keep up the amazing work! Rock on!

This is a great video and the visual animations are really helpful. Just subscribed ❤

[@JustMaiyak]

That quote at the end is one every programmer should know

[@etorty_dev]

"Remember that creation goes hand-in-hand with problems..." @9:44 Absolute truth. Excellent video @Coderized

[@Dragonofshame]

This is great, thanks. I get what you mean by these being guidelines and not really rules. I love the idea of making my code "cool" and designing it in a way that it's easily expandable, but I've come to realize that if I'm just doing a small project for college that needs less than 100 lines of code... Then there's no need to overcomplicate it by making it modular, or by writing it in a way that will never produce errors. If it does what it was meant to do and it's easy to understand then that's really all it needs lol

[@coderized]

Exactly right :)

[@Zoronoa01]

I was smiling when you said that it's worth it to see that smile :) I really appreciate your content Keep up the good work

[@emileriksen2074]

love the illustrations! great content

[@yogeshsingla131]

We want projects that get easier with time, NOT harder. Underrated line.

[@stephenmcconnell7868]

I had to smile while watching this video. I remember going to an interview and questions asked about EACH point you make. I messed up one of the terms in SOLID and they recommended a couple of good books that helped fill in the gaps. But this is a very good overview of what good coding techniques and practices should be. I have since retired from programming. The commute was around 1.5 hours each way and although I loved the company for which I worked, they didn’t encourage remote work. It’s too bad, because a couple of years after I retired, COVID hit and all development work was remote……. Oh well…. Timing is most always everything.

[@NicoFye]

I am curious at what age have you retired, if you don't mind me asking

[@KnightZephyr]

Wow, this so good! Thank you so much for making this video, this definitely is going to help on my coding journey.

[@thetaseries4179]

The animation and representation of concepts is very nice. Quality content.

[@sethbrokalis9824]

I normally don’t comment on videos but I wanted to say this video was amazing! With the absurd quality, I was thinking the channel had at least 100k subs. If you keep it up, I’m sure you’ll be there in no time!

[@coderized]

Thanks so much! Means a lot :)

[@jugzster]

The animation is lovely and impressive! I see your CGPGrey reference 🙂

[@CraigSchubert]

Thank you for this! Looking forward to checking out more of your content. 🙂

[@jeromebastien8622]

Great video. Thanks for the advice, already knew most of it but especially the thing with time was really eye opening for me while I’m currently working on a long term Project and stressing myself to an extend where it’s not healthy anymore. Got me thinking about how to approach the further development of the project. Subscribed at like 3 minutes into the video lmao

[@apolloapostolos5127]

I started implementing these last week as a complete noob 😁 I got discounted enough with my typos that I simplified as much into variables or designs I could change recursively in the script. . Change One and Multiply That was my approach. . I enjoyed this video. Both validating and provided me more perspective.

[@purewantfun]

Maybe another point that ties into proper naming: using proper types. They serve both as documentation and for static analysis tools. This saves you so many debugging sessions where you get unexpected values, because your editor/compiler will scream at you if you get it wrong. It also provides immense benefits to the rest of the team as they are able to inspect the shape of the data that comes out of your functions/methods.

[@coderized]

Types in general I totally agree with. Types make code way more robust and predictable. Types in names, I think is unnecessary - though I'm not sure if you meant that

[@lawrencedoliveiro9104]

Hungarian notation? Just say no!

[@johnsmith-ro2tw]

types is an obvious one. I would add using something like jsdoc (or the equivalent for other languages). If the functions are poorly written/named, then at least you get hints what the guy before you tried to do as he will have put a little effort to explain it using plain sentences.

[@purewantfun]

@@coderized Definitely not in your variable names, wouldn't want to make refactoring the codebase impossible for the next dev that comes along 😅

[@Firestar-rm8df]

@@coderized I disagree on this point actually. In general the video was great and by n large you are pretty safe to apply these broadly, but I have and will continue to argue for types in names until analyzers like Visual Studio's Intellisense can quickly and accurately deduce the type for me. I find that it often makes errors in more complex function and data structures, or when dealing with multiple typedefs/alias, or when meta programming becomes too advanced. Sure if it's a function local and it's a 30 line function, leave the type off, ok. But if this is something you are going to be passing around, exposing in an api, overriding, aliasing, or something, PLEASE use a type. I do not want to have to manually jump through 30 headers(or what ever your language of choice uses to resuse code files) just to figure out that *age* is a string and not an integer. And in larger programs, I don't want to have to run them and reach that point in the debugger either. Depending on the system that isn't even practical. I think there is a strong case to be made to leave types in names at least most of the time. Yes sometimes you can omit them, but I am far more likely to waste an hour figuring out where something is actually defined to look up the type than I am to struggle for an hour with the readability of your code because you went overboard and stuck a type suffix on everything.

[@larseneivind]

Thank you and thank you youtube for suggesting this video and channel to me. keep up the good work!

[@priyamgarg9488]

I'm using these rules for last one year it's just so helpful. Can't think of writing code without using these now

[@ojovemdev]

Your video pretty much summarized everything I've been studying for the last couple of years or so, and STILL managed to make me understand everything in a fuller yet more simpler way, cheers man, your channel is bound to be successfull

[@coderized]

Awesome comment, thank you!

[@pingusdingus99]

Did 11 minutes really pass me by? Great video! I'm amazed this is your first video on this channel it feels like you have a well defined style and I love it

[@harrison3973]

this is a lovely video. I'm planning on doing a very intensive coding bootcamp very soon (i'm a complete beginner who only knows basic html), and your videos are so valuable.

[@honestfxpredator7903]

Nice easy to understand summary of the main points of coding. Currently half way through React on my front end development journey, you’ve got my sub

[@ego-lay_atman-bay]

I'm working on the largest project I've ever done, a python library for modding where's my water, and I've actually been doing some of these things already. I've actually been doing stuff in this project that I don't normally do, such as, splitting mostly everything into its own file, aka module, and I have found that it can be easier that way. I've also started using constants more, especially when I want to check if a value is the default value.

[@explosionimplosion4679]

Oh hi lmao I know you from Scratch I'm @--Explosion--

[@tabsc3489]

Thank you for this awesome vid, great advice, and gentle guidance. Always so nice to have positive feedback that doesn't coddle the programmer nor attack them for simply not knowing. Smooth and relaxing animations that ease everything into context. Definitely subbed and looking forward to more of your content!

[@steppen6860]

Your videos are incredibly helpful! Thank you!

[@TenHorizons]

I'm surprised this is your first video! It was great, and I find myself wanting to watch more! Looking forward to your future videos!

[@Shelly-kx2wz]

everything about this was perfect, the pace, the animation, the narration. Just keep these videos coming. Also I would like request an in-depth video on patterns. ❣

[@carlmeyer96]

Dude just want to say these animations were fire! 🔥 made each concept so much easier to follow and understand 😁

[@jameslangbein1471]

Incredible production quality, awesome content, keep it up! This is one of the best videos I've ever seen on this subject!!!

[@coderized]

Thank you James!

[@corv2731]

As a new programmer (about 6 months in) this is extraordinarily helpful. I am going to watch this several more times. I'd love to see you go into more detail about some of the things you listed out- like going into each one of those design patterns you listed for example. I also might include in this video- COMMENTING! Sometimes I just want to get an idea out that works that I intend to fix later, but then to your point, I end up forgetting what it does or why I did something a certain way if I haven't written comments to myself. But anyway, great video, thanks!

[@monsieuralexandergulbu3678]

4:57 not the square hole 😂

[@ninjmaster5609]

I love the subtle interne memes in this video

[@NaviListen]

I love that when you gave an example for Single Responsibility, you took apart a Util class. My Hell, the number of programmers I've worked with in my career who just stuff everything into a Util class is *too damn high*.

[@martapfahl940]

I don't know if it is your voice or the quality of your microphone but the overall quality of your audio and the whole video is stunning, thank you my friend!
