these videos are *money*. Perfectly spoken english at a confident pace with easy-to-understand concepts is such a rarity to find--easiest sub of my life! Love the framework-agnostic videos!

Wow, you just absolute sold me on TypeScript. I come from a Java background, and this is all I ever missed in plain JavaScript!

[ikezedev]

Object oriented /functional programming in TS please.... I love this one 😍

You are such a good teacher for those who really want to be a good coder, I love your videos thank you so much for this.

I have been using Typescript for a bit but always learn something new when watching your videos. Today it was adding a key property to an interface to allow classes implementing that interface to include additional properties. Great video!

[JMRolf]

Been using it for like 3 years now. Loved your overview. Will share this with some of the junior devs on my teams. Thanks!

Feeling this. I think it's the first clearly communicated TS tutorial that hasn't left me banging my head against the desk.

This video was incredible. TS looked so complicated but I UNDERSTAND IT NOW. Ten minutes well spent. Thank you!

Wow, thank you for this awesome intro to TypeScript! I have been working at an internship this summer, and yesterday I ran into some TypeScript. I had a background in JavaScript already, but I searched for a crash course just to be safe. This came up first, and in twelve minutes, I got a good handle!

Best concise beginners intro tutorial ever on typescript, with best practice! 😊 I like your no BS approach, straight to the
point. 😊 You're blessed with the gift of teaching! Keep going 😊 We'll applaud you. 😊

Fantastic! Please do object oriented vs functional. I've been using TypeScript for years and I learned a few things... Your videos are consistently great!

[HdeHidratado]

This video presented me to Typescript. After sometime learning it, I now have a full time job in development. Thank you very much. This and many other of your videos helped me so much to get were I am today.

[Archnemesis]

As I become a better programmer, your videos have become some of my favourites. You give a nice birds eye view that makes diving into documentation way easier!!!

[alexcubed]

This video was incredibly helpful! I have known about TypeScript for a while but never really understood what its use was over plain JavaScript. Now I'll probably start using it more than JavaScript.

One of the best channels! I really like the way you explain, edit the videos and keep your screen clean. Please, keep that quality. I was planning to learn React, but since your videos are so cool I'm now thinking to learn angular. Just because wanna see more videos on this channel.

[DEVDerr]

Lol... Finally now there is a video with most practical use cases with TypeScript functionality and best shared experience with this technology ive seen so far. And its not boring, even if i knew this stuff already. Like button clicked, good job buddy! Keep going.
P. S I'm definitely waiting for OOP. That's going to be amazing.

Hey, great tutorial. Been using the ES6 version of JS in both frontend browser-based apps and backend NodeJS apps for some time now and whilst its marked improvement over prior versions (owning to the first class support for classes, objects and inheritance, etc) one thing that its missing, in my view, as an engineer used to working with fully fledged backend languages (I, e Java, Go, etc), is Strong Typing. String Typing is useful for many of the reasons you cited in your video, principal among them: the ability to detect type mismatch (and related) errors at compile time rather than at runtime, which in and of it self may go some way to preventing the occurrence errors that can be incredibly difficult to reproduce and diagnose.

I also love the fact that Typescript is essentially backwards compatible with JS, on account of it being a super set of the language; I may actually use Typescript on my next project and that is, in no small part, due to the clarity and intuitive exposition of this tutorial. Thank you!

[KaushikRao]

Thanks Jeff for an awesome content as usual. Love your tutorials and the way you explain. This was more useful.

I've been busy with C# and JS all day today. I'm basically burnt out and then YouTube recommenced your video and I enjoyed every single second. TS has been something I've had my eye for a while and this video just made me want to go out and give it a go.
