Mo> as learning any language ( obviously I am not C adept) what does ~& or
Mo> even just ~ mean negate a bitwise?

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators

'~a' inverts the bits of 'a'

'a & b' returns ones in positions where both 'a' and 'b' have ones

'a & ~b' returns ones in positions where both 'a' and the inverse of 'b' have ones

'a &= b' assigns the result of 'a & b' to 'a'

'a &= ~b' assigns the result of 'a & ~b' to 'a'

'a | b' returns ones where either 'a' or 'b' have ones

'a |= b' assigns the result of 'a | b' to 'a'

So:

var a = 1; // 00000001
var b = 2; // 00000010
a |= b; // a = 00000001 | 00000010
a &= ~b; // a = 00000011 & 11111101

if that makes sense.
