  1. I only use JavaScript in web pages, not in the back end (my preferred language for that is Python). So far I’ve only needed maybe a couple of hundred lines of JavaScript at most at any one time, and writing it directly has been quite tolerable.

  2. I don’t use TypeScript. Looking at those examples in the video, it really looks like Microsoft has brought C++ to JavaScript.

  3. I have only so far used type annotations in Python as a documentation aid. None of my individual Python projects has gone much over 10,000 lines so far.

  4. Annotations would presumably be like in Python, where the compiler simply collects the information, attaches it to the constructed object, but otherwise ignores it. It is left to additional lint-type tools (e.g. MyPy) to do the actual static type checking.

  5. Is that a Microsoft thing? I use Emacs, which doesn’t do squiggles (though there is probably a module for it somewhere). I don’t even have syntax colouring enabled.

  6. There is static type, there is dynamic typing, and there is no typing at all. JavaScript is one of these.
