A bitwise operator is an operator used to perform bitwise operations on bit patterns or binary numerals that involve the manipulation of individual bits.

Variants

And

Performs the AND operation on each pair of bits. a AND b yields 1 only if both a and b are 1.

Syntax: x & y

More information:

• ECMAScript reference
• MDN documentation

Or

Performs the OR operation on each pair of bits. a OR b yields 1 if either a or b is 1.

Syntax: x | y

More information:

• ECMAScript reference
• MDN documentation

Xor

Performs the XOR operation on each pair of bits. a XOR b yields 1 if a and b are different.

Syntax: x ^ y

More information:

• ECMAScript reference
• MDN documentation

Shl

This operator shifts the first operand the specified number of bits to the left.

Syntax: x << y

Excess bits shifted off to the left are discarded. Zero bits are shifted in from the right.

More information:

• ECMAScript reference
• MDN documentation

Shr

This operator shifts the first operand the specified number of bits to the right.

Syntax: x >> y

Excess bits shifted off to the right are discarded. Copies of the leftmost bit are shifted in from the left. Since the new leftmost bit has the same value as the previous leftmost bit, the sign bit (the leftmost bit) does not change. Hence the name "sign-propagating".

• ECMAScript reference
• MDN documentation

UShr

This operator shifts the first operand the specified number of bits to the right.

Syntax: x >>> y

Excess bits shifted off to the right are discarded. Zero bits are shifted in from the left. The sign bit becomes 0, so the result is always non-negative. Unlike the other bitwise operators, zero-fill right shift returns an unsigned 32-bit integer.
