I don't think it can be overstated how important Satya Nadella's approach to the CEO role has been for Microsoft. Just a few more years of Ballmer and I believe MS would have been toast.

As someone who made the switch from game dev to web dev. I really appreciate the work done by the typescript team and angular team. The switch was such a breeze.

Thoroughly enjoyed this documentary, gave me great insights into the development of TypeScript and its grandiose effect on web development and the open source culture. One suggestion: When a novel concept is being talked about, be it structural typing, decorators, or Flow, would be cool to pair the interview with a visual depiction on the screen. Makes it easier to follow for those who don't know those things by heart.

Documentaries like these remind me that there is great man power behind the tools (we) developers use everyday. Much respect to Microsoft and those who helped build Typescript.

Really great vid! I remember when I first used TypeScript in 2012, I was in the Bing Team as a junior engineer and i just updated a new build step to include TypeScript cause I wanted to use it since the webapp was getting complex. I eventually helped all Bing teams to migrate to TypeScript, very nice seeing everyone jump on the same boat.

Mr Heilsberg made all the difference in my life. First with Turbo Pascal (which I also pirated), then with Delphi (which I also pirated) and then he finally made a product that I love that I don't have to steal! Thank you, sir! I wouldn't have been the developer I am Today if it wasn't for your creations. I owe you more than one.

🔥 Big shoutout to the incredible TypeScript Team and our amazing open-source developers! 🙌 Your dedication and hard work are changing the game. Much love and respect to all of you! Let's keep pushing the boundaries together! 💪❤ #TypeScript #OpenSourceRockstars
I like this video a lot. The constant hand-gesturing present throughout the entirety of the video totally didn't mess with me at all. And my absolute favorite engineer ever, Shaundai, does an absolutely fantabulous job elucidating the ubiquitous nature of TypeScript in contemporary frameworks and necessity of a good ecosystem for a technology to thrive! Her portion was definitely my favorite in the whole video, 11/10!!

I don’t think it can be understated how important typescript is. I know a lot of people fight it, I had to fight my company at the time, but once it’s in place it makes it easy to collaborate and refactor code. I got it into a small high priority project with 12 week turn around time with 7 devs. And we delivered before the deadline and a lot of that was catching breaking merges and quick refactoring.

I feel like a baby because I've only used ts and this is all I've known and expected. The only times I don't get this experience is when I have to use a repo that was badly written with anys and Function types everywhere

Great documentary. As a Golang developer, TypeScript solves problems I don't have in ways I don't like. But am happy that it exists, and DHH loves type gymnastics too, for obvious reasons.

@rogersanctos 2 months ago
Most of tools I can use those days came from this new age Microsoft. Most of them were like inaccessible before there. A lot of things were harder to accomplish. Not only languages, language supersets, IDEs, frameworks, Language Server protocols (LSP) and their already done language servers made my life, and I think the life of a lot of programmers, a way better. That's why I am so grateful to everybody who helped this day to come. Opensource, even nowadays being like a big companies war, evolved so much after that. And, eventually this philosophy will get better and better (so I hope).

Excellent documentary. I remember when Jonathan Schwartz tried to open source Sun software (starting with Solaris). I thought it was an excellent strategy and saw the power in it. Unfortunately for Sun it was too late. I'm glad to see Microsoft eventually understood what open source community was about.
Thank you for this remarkable documentary! Really enjoyed watching it!

and another one *As soon as you will start understanding typescript you will stop hating it. This is exactly the moment when you will start to fall in love with this approach and see a new possibilities and adjustments to your workflow that will allow you to work more comfortably. I used to be a hater of typescript, but I wasn't even coding in javascript back then and when I decided to try it out and started to understand it, I just fell in love and never went back to plain javascript. The fact that you can have unions, with autocompletions that you can structure your data, its incredibly powerful*

@GulshanurRahman 2 months ago
The single best decision TypeScript made at the beginning, in my opinion, is to make the language and the tooling together. Those two aspects of TypeScript complement each other so much! And also, the VSCode obviously, to showcase that tooling aspect. One day, I wish the "language" part of TypeScript to be merged into JavaScript, and the tooling aspect to become invisible, within the editors and IDEs or bundlers. Then in the JS ecosystem, it will be invisible, but everywhere!

I like how dog food has become a verb as in "We don't just dog food our own language but we also dog food our own develoment environment." at 15:37 and this is understood to mean using your own product. Future etymologists will be amused.

*1:05:35* this i think is a critical point, there's *typescript* the *syntax* and typescript the *tool* , not everybody consciously uses typescript syntaxes but everyone who writes javascript in visual studio code is using typescript; it's only natural because vscode is built with typescript.

Finally finished watching, great work guys, hope to see your channel grow with more great documentaries! If you allow a little piece of feedback, the last half an hour or so of the movie feels a tad stretched, with different people kind of repeating the same things. It doesn’t make it significantly less enjoyable, but I thought you could use that input anyway. Keep it up!

@conor909 2 months ago
They're talking like it's this great success story, when it's very far from being finished. The user experience coming from JS is awful, it's even worse knowing the creators also built VSC. So why did you give us this tiny window that you can't scroll all the way to read errors in? And the errors messages use a foreign language then what JS devs ever use, it prints the full obfuscated object code when saying "the object {...} is not the same as {...}" when we only really just need the incorrect property name(s), you cant use some functions like array.filter without loosing the original array type or a spread operator. ..I could go on and on. But yes I use it and love the features. But it seems to be the definition of a product designed by developers - works for them but not the users (they're not JS users)
