>> in javascript

I’m going through some code and I ran into 2 weird operators: >> and <<,
in the form of 2<<3 and 442132132>>546542132.

I deduced that x<<y means x times 2 in the power of y. Meaning, 4<<3 is 4*(Math.pow(2,3)), which is 32, but I couldn’t find what x>>y means.

I know it usually returns 0 for small numbers, but when high numbers are involved, the result is usually a small number.

Answer 1

From Mozilla:

Left shift a << b Shifts a in binary representation b (< 32) bits to
the left, shifting in zeros from the right.
Sign-propagating right
shift a >> b Shifts a in binary representation b (< 32) bits to the
right, discarding bits shifted off.

442132132>>546542132 seems excessive for a number that is only 32 bits wide.
