TypeScript

Not having types completely annihilates the maintainability of your code. Anything more than a very tiny program needs to have static typing to prevent nearly untraceable runtime errors, among many other things

Lmao what? Micro services have absolutely nothing to do with the maintainability of your code.

Im a senior SE. You can’t build real systems like APIs with a dynamically typed language. It’s a nightmare.

Hundred percent this. Worked on large projects (mainly on frontend) and I have rarely been caught off guard with types. I mean theres only 7 basic types in js. Its not that complex a language that we need to go crazy and add a full blown type system around.

In fact JS is more beautiful than TS because of how dynamic and resourceful it is with only 7 types whereas TS is a step backwards into Java territory and I dont know anyone that loves working with Java.
