Cross product is a scalar in 2D but a Vector in 3D?

Hello, could someone explain why this is or maybe im wrong?

Documentation seems correct on its return.

The cross product doesn’t exist in 2D. Correction: it exists but doesn’t mean the same thing, it is more like the dot product.

Wait can you tell me why this is exactly

edit: alright, damn vectors are so confusing…

This the best explanation I could find, so you can use it for similar purposes as the 3D cross product:
