What do these JavaScript bitwise operators do?

by 
<<, >>

Bit shift left and right, respectively. If you imagine the left operand as a binary sequence of bits, you are shifting those to the left or right by the number of bits indicated by the right operand.

&, ^, |

These are bitwise and, xor, and or, respectively. You can think of & and | as the counterparts to && and ||, except that they will treat their operands as bit vectors, and perform the logical operations on each of the bits. There is no ^^ operator, but this operation is “xor” or “exclusive or“. You can think of “a xor b” as “a or b, but not both”.
