[@tedo5400]

Hey mosh can you please make a video of laravel

[@mykun8737]

Hi Mosh, The python course you teach is great but I found the content in the course very basic and it lacks many important things like decorator and multithreaded, asynchronous programming in python

[@raphael3806]

Dm for more info

[@LuisMartinez-se2np]

Lately i've been learning typescript from scratch courses, but this one is far one of the best of them, because you explained a lot about the tsconfig.json. and all the datatypes, if this happened in just an hour i can't wait to see all the complete course on your platform, thanks for sharing this bud, we really appreciate this!

[@jdholwick]

I am finding this intro to TypeScript very well-designed, attention-grabbing, and educational! I have a four-year computer science degree, and I am trying to expand my professional resume. Thank you for this course!

[@CodeWithClinton]

Your 6hour Python video on KZbin was where I learnt the basics of Django. I fell in love with Django and started teaching Django on my KZbin channel. Sir Mosh you are the best instructor in the world.

Same here. I literally learnt in a day.

[@programmingwithmosh]

You're so kind! Thank you! Please support me by sharing this video. :)

[@hiranga]

@@programmingwithmosh Great vid Mosh - I'm still going through this step by step. Is it normal that I have to run `tsc` in terminal, after each `index.ts` edit + save, before starting the Debug Process? I'm fumbling a bit around the 22:00 minute marker

[@victoronofiok520]

Facts❤️

[@zeenmc]

So true...

[@theSoberSobber]

@@hiranga hey, i am a bit late, but you could either set watch to true in tsconfig or run `tsc -w` in the shell. If your out files are supposed to run on node then you may also use ts node in chain with watcher. Otherwise you may use a live server for browsers! Hope this helps!

[@voiceoftreason1760]

I really like this idea of progressively enabling compilation errors as you learn the language so you aren't prematurely thrown in the deep with cryptic compilation errors

[@ItalCad91]

With every language and programming tool you have a lot to learn, but you summarize the most important concepts so that we can begin doing real work with what we learn, something that most courses fail to do. You will find that other guys teach everything from A to Z and most of the time you will get lost or discouraged because you do not see the point of what you are doing in practice. Using your one-hour tutorials, you achieve the opposite and you still learn a lot. So thank you

[@stand777]

Excellent tutorial! I am a seasoned core Java developer and am just starting to get my toes wet with React and TypeScript. I tend to get impatient with these type of tutorials, because, usually, too much time is spent on the basics, but the pacing with this one is perfect! Thank you!

[@Ramkatral]

This was honestly just the right amount of information and just the right length for a JS dev to sit and watch through and be ready to start using TS without having to dig too much into the docs.

[@chisomodimmegwa3479]

Wat i was looking for. All other tutorials are too long. Only need the basics and u'll expand on your own when doing projects

[@user-km9xe1df5k]

The way you explain the fundamentals is really engaging and encouraging me to start using TS, it is not as frightening as I've expected. Thank you, your videos are awesome!

[@ksaurus]

One of the best, perfectly-paced, Typescript tutorials out there. Unfortunate that you don't use curly braces with your if statements. One of the biggest causes of bugs for new and even experienced JS programmers. Hubris is the only reason not to use them.

[@aamirbhat650]

Fantastic TypeScript tutorial, Mosh! Your video provided a clear and comprehensive understanding of the language. The way you explained concepts, from basic types to advanced features, was incredibly helpful and easy to follow.

[@pipio4593]

Mosh just gave me hope that understanding programming is not as difficult as I thought. Thank you, Mosh.

[@_achalsingh]

I've been waiting for your - The Ultimate TypeScript Course - since ages Mosh!! Looking forward to enrolling in the same!

[@Shinee3e]

My personal opionion is at first i felt a bit skeptical about your content, cause its not specialized on anything (python, c#, js, react, ml, docker...) but after watching couple of videos I've noticed that its really good to get a solid introduction into a certain technology, build up a good idea of it and go from there. Thanks

[@netanelr.yesharim3828]

I looked everywhere for coding instructions that are easy to understand . It shows that you know what you are talking about. Thank you!

[@israel4961]

you dont need to go to Harvard to learn programming. mosh is the expert on teaching programming than any universities in the world. trust me i am witness. i used to be one of the people who dont understand coding and got lowest grade in university. but i decided to quit college and bought all his full stack courses. now i fall in love with coding and becoming the best on the field. Thanks Mosh!!

[@linmus2370]

Thanks a bunch for such a comprehensive crash course on TypeScript. It helped me a lot to brush up on TS.

[@dovudyusufzoda2216]

the most pridcutive video without time wasting explanation | examples. Understood typescript so clearly🔥🔥

[@gznqtl]

Hello Mosh, I am 50 years old, I love programming in C++ and Pascal when I was student (Maths). Now I am CTO in my own company with the new goal to integrate Web Dev. I need to understand JS and TS urgently to speak with the developing team. I have no words to thank you to help to understand the basis of these lenguages and how to used it. Please consider one of my favourites instructors and teachers EVER. Thank you for your effort. I will enroll to your full courses! Greetings from México.

[@karantrehan7710]

Mosh, your name will go down in history as one of the best teachers ever, if not the best. Wish you would teach other subjects too. Finance, Medicine, Astronomy, Physics, basically all things teachable. BTW, how about creating a course on System Design and other aspects of End-to-End software building and releasing? Really looking forward to something like that in near future.

[@rayatbinnasir6232]

Incredibly video. This was really helpful. Mosh's tutorials are always so neatly arranged and skips unnecessary contents. Thank u very much for this and hope to see more tutorials. 😍

Hey Mosh. I followed one of your courses and found it really helpful (html and css course). I was wondering if you'll manage to make a bootstrap video/course sooner or later.

I've been using Typescript for around 9 years (it was just under a year old back then and even then was friggin awesome!) and it's always very strange to go back to plain old Javascript. It always feels like something's missing!

Windows users...you're in for a nightmare trying to follow this tutorial. Not Mosh's fault by any stretch, but I've been at it for hours just trying to get the debugger command to actually mother flarkin work. Edit with my solution: Replace the preLaunchTask line with "console": "integratedTerminal"

Amazing stuff. I'm curious though on what would be your approach to setup the VSCode debugger having TypeScript installed as a dev dependency instead of a global dependency.

Thank you for your support! Hope you'll enjoy the course! :)

[@nav_9to5]

Hi Mosh, Thanks for creating yet another insightful and easy to understand video tutorial. I am an old subscriber and student of yours. I really loved your javascript course so I bought the node course as well. Just one thing lately since the start of Mongodb modelling lesson the syntax used are outdated and some other parts are outdated as well. It's a humble request to kindly keep on updating your courses so that it helps your students to keep on learning and subscribing to all the upcoming courses.

If you're debugging in VSC is not working just add this RED DOT (breakpoint) in index.ts. It solved the problem for me.

[@user-zh9li4bi3g]

You are a great teacher. That part of debugging did not work for me on my Windows PC. I spent two days on it, did a lot of , Google-ing, and finally gave up! Maybe someone can clarify beyond what Mosh has done. Thank you.

Quite disappointed to be honest to realize half way through the video that this is just an intro. I wish it was mentioned at the beginning so I could have decided if I want to take a free course or pay for this course. Teaching was clear and easy to follow.

fully focused introduction to typescript Much appreciated Mosh

[@mahdighiasi668]
