Bitwise Operators.

Bitwise operators treat their operands as a set of 32 bits (zero and ones), rather then as decimals, hexadecimal, or octal numbers. For example, the decimal number has a binary representation of 1001. Bitwise operators perform their operations on such binary representations, but they return standard JavaScript numerical values.

Operator	Usage	Description
Bitwise AND	a & b	Returns a one in each bit position for which the corresponding bits of both operands are ones.
Bitwise OR	a | b	Returns a one in each bit position for which the corresponding bits of either or both operands are ones.
Bitwise XOR	a ^ b	Returns a one in each bit position for which the corresponding bits of either but not both operands are ones.
Bitwise NOT	~ b	Inverts the bits of its operand.
Left shift	a << b	Shift a in binary representation b bits to left, shifting in zeros from the right.
Sign-propagating right shift	a >> b	Shift a in binary representation b bits to right, discarding bits shifted off.
Zero-fill right shift	a &&& b	Shift a in binary representation b bits to right, discarding bits shifted off, and shifting in zero from the left.
