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.

We all appreciate the efforts of the Typescript team

[@dopetag]

That is sick! Keep up the good work. Thanks Microsoft for VSCode and Typescript!

[@MicroUrb]

Yes indeed, Microsoft did good with VS Code and TypeScript, but folks thats no reason to drop Slack for Teams, it doesn't mean you take every single Microsoft product into your life now. Kudos once again though for VS Code and TypeScript, I live and breathe these tools everyday...even...now.

[@andrewmanyore9913]

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.

[@InarusLynx]

I remember being in my C++ w/ data's structures class in 2018 and my professor showing us Sublime. I was like "oh that's cool, let me check out some other tools." Then I stumbled upon vscode and python. Everyone was hyping them and I went "sure I'll check this out." I was instantly impressed with Vscode. I never looked back. Now that I'm getting heavily into Next.js, I'm very happy the more I learn about Typescript and the feedback I get without even running the code. Reminds me when I'd debug C++ back in 2018, having the ability to have so much feedback on my code.

[@devprocedure]

SO YOU SWITCHED TO WEB WORLD? I do NOT see "real-world" problem being solved by using TypeScript. All I see are silly examples of a "function that adds or divides 2 numbers' to justify "type checking". e.g., Who writes a function just to do basic math???? Next, developers are testing (aka runtime) their code LINE-BY-LINE anyway, so "compile-time" checking isn't all that beneficial in saving a developer time coding. In other words, TypeScript adds a layer of complexity that doesn't have that much benefit to JavaScript world. NEWS FLASH: 1. Most data on the Client Side are STRINGS anyway. 2. NUMBERS and DATES are already validated in the client's browser anyway. 3. And YES, you are passing data for a KNOWN REASON. So you have a pretty good idea what is to be expected. And those to say you don't OR say you haven't worked with a large code base are justifying passing parameters that you have NO CLUE in what you are passing? If so, that is a sneaky form of "job security". LOL. ADDENDUM: > You're passing it for a reason so will usually know what it is in the object at least type-wise. -ksh1997 "If you don’t see the importance then it might be because you have never been in a large project " Are you saying the name of the person passed in the parameter is too vague or misnamed? Or we should have NO CLUE what should be coming from that parameter? And that includes those of you who worked on a large code base as those of you who have, should have well-chosen names for parameters that describe what data is coming through. If so, why not give examples of "vague parameter variable names" that TypeScript solves in the REAL WORLD?

I saw that conference in October 2012, and I've been using TypeScript since then. This was great to see. Thanks for making this documentary! 💖

[@AqgvP07r-hq3vu]

This documentary is truly epic. Even after a year, I find myself coming back to watch it repeatedly. Although I no longer use TypeScript, the legacy and innovation of the TypeScript team-and the brilliance of the documentary team-will undoubtedly resonate through future generations of the software industry.

[@aram5642]

I might be wrong, but I can't beat this impression that I have just watched a 70+ min long film about TypeScript without a single mention of tsconfig. Correct me if I missed that. ;-)

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!!

[@codeaperture]

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.

[@JEsterCW]

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*

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.

I wouldn't have been the developer I am Today if it wasn't for your creations. I owe you more than one.

[@DavidsKanal]

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.

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).

[@devviz]

*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.

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.

[@csy897]

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

[@gorandev]

[@JeffryGonzalezHt]

Late to this, but it was really refreshing hearing people from Microsoft address directly the mistrust many of us had back around the time TypeScript was announced. My guess at the time was that TypeScript was just a way for Microsoft to keep Visual Studio relevant for people doing JavaScript. At the time, trying to do "plain" JS in Visual Studio was horrible - like worse than just raw dogging it with Notepad (or as was mentioned, SublimeText). It was really the introduction of the TypeScript language server that deserves special mention. Even today, pretty much every editor (even Vim!) works with TypeScript - and Visual Studio is still about the worst. ;)

That was so funny. I have no idea why they put a youtuber in there. This guy has extreme opinions on every technology "you MUST use this, DONT use this is absolute shit" he has no comprehension for advantages and drawbacks and lead thousands of juniors into a wall of fanatism. Poor casting.

[@ajml_hnter]

Really awesome 🙌

[@GulshanurRahman]

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!

[@ivanjermakov]

I agree. TypeScript would not be this popular without it's novel LSP.
