When you love a person that you have never met. I love you Tony and thank you for your JS and NODE courses on Udemy. I am thrilled to see that you have started to teach again. Please do not stop teaching. The way you explained types, coercion, scope/closure literally changed my life. Rare gem you are. Thanks again.

[@smartbuddythedeveloper9094]

Tony is a great guy, explain Javascript in such a depth and all of that in a simple word as well, i can bet no one else in the world can do so. I still remember when i graduated back in the year 2017 and searching for some good material to understand javascript that's when i come to know about this "Javascript: Understanding the Weird Parts" it is a priceless content recommended whosoever is looking to know all about Javascript.

If you do a tutorial about everything in software we wouldn't need any other video. whole tutorial milking industry would collapse :D

[@violarulez]

Seriously... he's above and beyond any other tutorials or walkthroughs. I find myself understanding even the most basic concepts in new ways. Not to mention the clarity of language in explaining. Too many other explanations have convenient logical leaps, inconsistent terminology, or over-reliance on abstractions. (Though I think he may have used the wrong "its" at 6:50 :p)

Hello Anthony .How are you doing ? I am truly happy to hear from you. Truly you have made me a good software developer with your teaching philosophy: "Don't imitate ,understand". And when always learning any new thing I have never stopped learning until I am 100% sure that I've understood the concept of it and I have sworn to myself to not never imitate but to understand .Honestly I am very thrilled to hear from you.:-))

The contents of the JS course are still valid, so I will be adding some new content for free to that JS course for now, rather than making a new one. Some of that new JS content will be also released as episodes of this series.

[@siyaram2855]

Tony there are so many courses that teach building apps but there isn't any course that helps you to think apps in terms of Data. So much emphasis is put on application part. If you see under the hood all we are doing is manipulating data. Thing would have been so much easier if someone could teach us to think in term of data and how they relate to each other. Designing schema for any app, would be so easier.

[@siyaram2855]

Hoping to touch 50k subs. Tony please answer this, do you think SQL is a programming language.

[@TonyAlicea]

Yes, absolutely. It is a declarative programming language, not imperative. People who are used to imperative languages tend to make the mistake of saying a declarative language "isn't a programming language", but that simply isn't true.

[@siyaram2855]

@@TonyAlicea You have no idea, I am jumping with joy seeing your reply. 🙃 Thank you so much for you the reply. It really means a lot to me.😇 Just a follow up question, CSS is also declarative, does that make CSS also a programming language? And What you have to say on the classic argument that HTML is a programming language? Will wait for your reply. I woke up and saw your reply. You made my day Tony 🙏😊

[@TonyAlicea]

@@siyaram2855 I think there is an argument to made that CSS is a type of declarative programming language, though it isn't as clear as SQL. I do not think HTML is a programming language. It's a markup language designed to add meaning to text and connect separate text documents, not to instruct a computer to perform a task.

[@MannyH80]

How do I make an app with a relational database? Do I always have to have data for an app? Can I use javascript with a database? Are there a lot of jobs for people to build databases?

[@TonyAlicea]

Hi Manny, good questions! 1) You build a relational database separately from building an app. Then you provide a way for the app to read data from and write data to the database. This is usually done via "API"s which are built in things like NodeJS or ASP.NET. This code lives on the server (not running in the browser or mobile device). 2) Not every app has data, but many many apps do. It depends on what the app needs to do! In general, if the user needs to give the app any information, you will likely have a database. 3) You can use JavaScript to build the "API"s I mentioned before, but writing actual database queries happens with SQL. You would want to investigate NodeJS more if you want to use JavaScript when accessing your database. 4) I can't speak to the current job market or market in your area, but generally speaking knowing how to design, build, and use a database (Relational or NoSQL) is a fundamental skill for web and app developers. Think of an app developer knowing how to work with databases as similar to an accountant knowing how to use a spreadsheet. Hope that helps!

[@MannyH80]

@@TonyAlicea Thank you for your reply. I will come clean. I am a full stack developer who owes much of his success to someone turning me on to your videos at a time where I was lost in bootcamp. Slowing things down the way you do helped calm my mind and deliberately move through the information I was receiving. I asked these questions from the perspective of someone who may be starting and not really know what a DB is yet. The thing I lacked for about first year of my career was a lack of understanding of how data flows in and out of an application. Once I really understood that part of what I was doing, everything became fun and I was able to take the language skills I learned from you and use javascript to manipulate, organize, and present data to users in a meaningful way ( I hope at least) I know this is outside of the scope of learning how things work on a deeper level, but is it possible at some point you might do a video providing a "high level" overview of why we need these technologies. I think something like that would be a great lead in to any of your videos. Thanks again for. your reply!

TIME FOR A CONCEPTUAL ASIDE

[@erenbagc7485]

I dont see any advantage of relational databases when there is MongoDB/mongoose. I am saving and pulling my data anyway I want without all this shit.

[@TonyAlicea]

NoSQL and Relational databases both have advantages under different circumstances. Relational databases, for example, can be more efficient for supporting reporting engines with many complex queries. NoSQL is better in other cases. Sometimes either is fine. Depends on the requirements of your application.
