Is TypeScript a fad or is my manager delusional? (feddit.dk)

I was talking to my manager the other day, discussing the languages we are using at $dayjob. He kind of offhandedly said that he thinks TypeScript is a temporary fad and soon everything will go back to using JavaScript. He doesn't like that it's made by Microsoft either.

I'm not a frontend developer so I don't really know, but my general impression is that everything is moving more and more towards TypeScript, not away from it. But maybe I'm wrong?

Does anyone who actually works with TypeScript have any impression about this?

No:

$ python

>>> def handle_foo(value: list[int]) -> bool:
...     return 42
... 
>>> print(handle_foo(False))
42

    I haven’t used Python since around the time when type hints first became a thing so I might be completely wrong here, but isn’t this because Python just generally ignores type hints? If you ran a static type checker like mypy over this it would complain right?

    Also, if you actually did anything with the list that you couldn’t do with a bool (e.g. len(value)), it would throw an error too because Python is actually pretty strict about types, just only at runtime. That’s why it’s usually considered to be strongly typed, although people don’t seem to agree what exactly that’s supposed to mean.
