Javascript Tilde & Two's complement

Question

Two\'s complement method - generates -(x + 1).

for example when JavaScript encounters the Tilde he uses this method:

~5 = -(5+1) = -6         


        

Answer 1

~5 = -(5 + 1) = -6

so far so good. However, ~ is not the two's complement, it's the binary inversion operator.

5     = 0000 0101
flip  : 1111 1010

which is -6

does that make it clear?
