I am glad I don't need to touch JS or web dev at all.

Now, I tend to use Python, Rust and Julia. With Python I am constantly using few same packages like numpy and matplotlib. With Rust and Julia, I try as much as possible to not use any packages at all, because it always scares me when something that should be pretty simple downloads half of the Internet to my PC.

Julia is even worse than Rust in that regard - for even rudimentary stuff like static arrays or properly namespaced enums people download 3rd party packages.
