  • TypeScript is still built on JavaScript, all numbers are IEEE-754 doubles 🙃

    Edit: Actually I lied, there are BigInts which are arbitrarily precise integers but I don’t think there’s a way to make them unsigned. There also might be a byte-array object that stores uint8 values but I’m not completely sure if I’m remembering that correctly.



  • Technically I think python already has an intermediate step that it uses before it starts running a script that compiles it into a lower-ish language (at least the cpython interpreter does this, it probably isn’t a part of the language specification though)

    The actual line between JIT languages and interpreted languages is pretty thin since I think most interpreted languages do something similar to minimize the amount that needs to be done at runtime


  • Screw it. Let’s actually make python script an ISA that gets run on physical hardware with no higher level tooling. Then we can have the python virtual environment which runs this for fools who don’t have the right hardware. Finally, when people start complaining about naming we make Python Script 2.1, which is a JIT language built on top of IL that looks nothing like either of them but can emulate both python and python script with the performance cost of being a quarter as fast as both.


  • Imo it’s context dependent. Obligatory “I’m only a college student/intern” out of the way.

    Whenever I’m working with a project with multiple languages (e.g. split frontend+backend, different connected services, etc.) operators like that can get blurry when they aren’t consistent between lancuages. Especially when one of those languages doesn’t have runtime type enforcement or has weird boolean behavior (looking at you JS/TS) which can lead to unintended behavior

    If everyone on the project is only working with that language, then your point is probably pretty close to the mark.
