Bitwise works on the binary level, so 0 on binary would seen as 0000_0000, and (in two's complemented) -1 is 1111_1111, this not 0 flips all the bits to 1s, thus alters 0 into -1.

These are the bitwise operators, all supported in JavaScript: op1 & op2 -- The AND operator compares two bits and generates a result of 1 if both bits are 1; otherwise, it returns 0.

7 The Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are some times used to improve the …

The expression x & y will perform a bitwise operation on each individual bit in x and y. So if x is 1010 in binary and y is 1100 then x & y will evaluate to 1000.
