Typescript is a type safe language that "compiles" into javascript. The Microsoft implementation compiles on save, so you work in your file.ts and a program running somewhere fires when the file is saved and converts it to file.js which you would distribute.
I haven't used it yet, but the demo from Anders looked good. It's an attempt to fix the "loosey goosey" nature of javascript. I would be great if browsers supported it as a built in language.

If you watch the video, you'll notice the argument notation is name: type rather than type name. I think Anders is reminiscing about his Delphi days.

ActionScript and the proposed ECMAScript 4 also use the name:type notation, so there is definitely some prior art in the web sphere
- kayoone 10y agoThats not really what he asked though. If in the end a developer can work 98% in TS, do they really care if it runs as JS or something else if it solves their problems with the language ? I have heard from people that love TS, but surprisingly many that also prefer pure ES6 JS.
- Clubber 10y agoThe only concerns I would have is I believe you have to debug the javascript rather than the typescript.
- thomasrognon 10y agoYou can make the sourcemaps refer to the TypeScript code. I set breakpoints in TypeScript files and step through it all the time.
