A definition of the ^ operation in javascript

Question

Can't seem to find a definition anywhere.

Typing into the console I can see...

  5^4 = 1
  5^3 = 6
  5^2 = 7

Any ideas why?

looks like the bitwise [XOR operator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators#Bitwise_XOR) — Rhayene, Sep 22 '19 at 23:23

It's a bitwise operation, ^ specifically does a XOR operation on the numbers.
