Numbers are simple - int or float . The operators work similar to python, except the case of // which doesn’t exist in JS. To get the same method as Python’s // or the floor, we use Math.floor().
let x = 12
x+x-x*(x/x)%x // all vaild, returns 24
x**2 // returns 144
x//2 //doesnt even make sense because '//' is comment in js
