Really interested in your experience with this.

What would you say it is about TypeScript that makes the code harder to read as it becomes more complex? Just the additional type annotation syntax, extra concepts like generics and/or the accompanying more exotic features of TS, the type definitions physically adding many lines of extra code, something about TypeScript that encourages code to be written in a certain way that is different and more complex?

As I remember, the biggest thing is the tendency of TypeScript to result in deeply nested code, which is very hard to read/unwind.

Note that I haven't touched TS in about two years now, so my memory is a little fuzzy.

Would this be in a different way to the equivalent JavaScript code? Or do you just mean like physically, the layout of the code with the additional TypeScript syntax makes it appear more nested/indented and more difficult to parse?

TS doesn't really do any worse than JS in this respect; the key here is the difference between either of them and Python.

Ah, this is a facepalm moment in that I had completely misread the initial comment not as being a comparison of JS/TS to python, but of JS to TS then a further comparison to python. Now it makes much more sense!
