Built-in Vector library
It would be great, if TIC had vector2, 3 and 4 libraries built in the same as math or table
Are those part of Lua stdlib?
Not sure
What are these libraries? Just 2d/3d/4d vector math or?
Almost, its just regular vectors that can help to calculate different values without need to search for the vector code yourself.
for python there is a built-in module linalg for tic80 that provides common 2d/3d vector operations and 2d transformations via mat3x3.
from linalg import vec2, vec3, mat3x3
Inspection below.

for python there is a built-in module
linalg is not a Python built in, you need to install NumPy to get it. Which is a huge package.
Are those part of Lua stdlib?
No, but there is a library that can be used: https://github.com/anaef/lua-linear/tree/master
BTW I agree that most of the people implementing at least 2d vectors to create something serious.

Yes, it is not a standard built-in. linalg module is only available in tic-80's python version. Check https://pocketpy.dev/modules/linalg/. Create a python project and it is available.
