I was missing Java because of how strongly typed it was. I was afraid of learning typescript because I thought it's hard, but this man teached it in couple of minutes! What a legend. Edit: corrected one word
@ChoppedBlade typescript compiles down to JavaScript. It can compile down to browser compatible js that uses the dom, or Node.js Javascript that uses node apis like fs, http, etc. That doesn't mean it's the same as nodejs
These videos are Gold, 1. includes almost everything you need to know for day to day tasks. 2. to the point without wasting any time. 3. English is very clear to understand and words are chosen very wisely. 4. easily and useful example so you can understand code fast and better THANK YOU VERY MUCH
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.
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!!!
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!
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.
I didn't want to learn Typescript but after applying for jobs and seeing it as a requirement, I had to check it out and I've become interested in it. It is super powerful and the learning is quite easy. The data typing is quite similar to Python’s code hinting and annotation. Glad I saw this vid.
I fell in love with TypeScript almost as soon as I heard about it. An unexpected benefit of TypeScript is you can now learn C# very easily if you want to. The syntax are very similar.
I have so many regrets as a junior developer. I contributed a bunch of angular 7 code at a startup I work at. I had no web development experience, but regardless I needed to finish my tasks as they're assigned, so I mostly focused my efforts on learning the Angular framework (which I absolutely love tbh) and the bare minimum JS. God the web project has gotten so big now, and I really wish I fully embraced the typescript... Future junior web devs out there, heed my warning: don't neglect TS! I feel like I'm stuck conforming to bad habits for the sake of consistency.
thanks a lot for ur words. i am just starting with web-dev; & as i already over complicate _alll_ the things a lot (just for this correctness sake) i was thinking of giving myself some slack for choice of *script. but thanks. ur words have steered me in right direction in this area too.
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!
Its just AWESOME. Instead of 1-2 hours basics, you have covered most of typescript in just 12 minutes. Beginners should also go through this video so that they can jump off to other concepts in very less time. +1 for this short and sweet but effective video over Typescript. I have watched your other videos also , you are AWESOME man. Straight to the point and you have not more that 15-20 minute videos. Great job dude. Keep it up. Liked it.
I've been busy with C# and JS all day today. I'm basically burnt out and then TH-cam 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.
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!
thanks so much for every single tutorial. I was smashing my head on the wall day and night and couldn't sleep well because I did not fix the error! thanks so much
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.
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. 😊
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!
JS devs that are hesitant to learn TS because of the "extra code" will realize the amount of time saved from out of the box auto-complete with documentation + compiler errors instead of nasty runtime errors is worth it 100 fold. Plus the extra code is only if you want to adopt typescript features....if you just decide to write vanilla javascript you can and you'll still get the benefit of the typescript compiler catching a lot of potential errors for you.
as more of a java/scala programmer, coding in js is my nightmare because there is always all kind of unexpected nasty stuffs that happens at runtime that could be resolved earlier and easily.
I'm just thinking what should be my next step as a software engineer and I was thinking about TypeScript. Your tutorial really helped me feel that this is the direction i would like to go!
One of the greatest advantages of people coming from the Angular 2 framework. To know TS out of the box. I love to use it with React and Node JS services and share models of objects back and forth in a mono repo.
Another great video from Jeff. This video is great as a soft introduction to TypeScript, and why is it very useful. And for the next TS video, OOP in TypeScript will be "sequel" to this video.
This was excellent. I would really love to see the object oriented/ functional programming in TS episode. That's been an object of curiosity for me lately.
Like you, my main reason for getting started to learn TS is Angular. It's time to learn both, because I don't want to only know and use React. I was interested in trying NestJs for the backend too, but lacking of TS skill prevented me. I read that Deno supports TS too.
This video helped a lot. Like you, I didn't even want to start learning TypeScript, but I was kinda curious what it's all about. I'll now use TypeScript as well xD
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.
Wow, Those 12 mins are the best 12 mins invested in my life ! I felt like I am on The Matrix. :-P Learn TS in 12 mins :-D Excellent video and very well explained the most important concepts.
Finally i really understand what is the use of and the [varname?] thank you for making this video. Please do the oop and functional programming for typescript
I started working with react after working with angular/TypeScript for more than 1 and half year , the react project wasn’t configured with TypeScript and it was a nightmare figuring out what is being passed to what and what is expecting what and why. There were n amount of type issues everytime TS is a bless for stability and readability
It was an awesome news, but unfortunately our project wasn’t configured using create-react-app boilerplate :/ but yeah good news for people starting doing things
One piece of advise for any new/beginner web developer. Don't jump to TypeScript just yet. Take the time to properly learn JavaScript and then start using TypeScript to improve your code and workflow... if it becomes necessary. At the end of the day, JavaScript is king on the browser and if you want to be a competent web developer you simply must know and understand JavaScript well - in the same way you should learn CSS properly before learning LESS or SASS.

Edit: corrected one word
I was thinking, “so this turns JavaScript into a real programming language. Cool.”
@ChoppedBlade but... Node can use typescript? And node only runs on the backend? What are you even saying?

really good video. it doesn't spam you with opinions and perspective. but actually show you stuff. great
I like your videos which forces me to focus more as it is in the perfect speed mode. Looking forward for the TypeScript Deep dives...
very similar to how php handles typing. love it. I didn't know that typescript was just extended javascript. that's actually amazing
Fabulous video - really good overview of TS. You lost me slightly on the observables bit at the end, but I can look that up.

Learn TS in 12 mins :-D
Excellent video and very well explained the most important concepts.
Amazing explanation, I subscribed right away. I hope to learn as much as I possibly can from your videos
Things nowadays are getting smarter, and less clunky. Thanks for the video.
I just watch your Videos before messing out with languages. Too good
Great video! Please continue the TS series.
Great intro video. Excellent examples that show the cause & effect. I could already infer the syntax mid-way thru the video.
Wow this is simpler than I thought. Great tutorial.

Very easily understandable language, Thank you.
Finally i really understand what is the use of and the [varname?] thank you for making this video. Please do the oop and functional programming for typescript
I would really love to see more of these videos, as I'm very new to TypeScript .
Rocking it again! Absolutely smooth and most efficient intro to typescript.
They should put a link to this video in the middle of Angular's Hero tutorial, so many things make so much more sense now.

Love your articulated vids that get me started with new concepts n frameworks . Time to do some TS on my projects ☺️
Wanted to subscribe only to discover I already did before now😄 You covered so much in so little time 👏👏👏
Really loved the video, It would be really helpful if you make an entire series on typescript
Good and quick explanation. Maybe you could also do a video about Flow and put it with TypeScript into comparison.
That could be cool. Maybe throw Reasonml into the mix as well.
This covers my typescript daily basis.
This was very well done looking forward to object oriented vs functional programming
