I am working on a mobile app, it needs to do bit shifting at some point of the code.

I ran into a bug which is certainly puzzling, and if I do it on Python it runs well.

JavaScript:

1000>>32 // resulting in 1000

Python:

1000>>32 // resulting in 0

Why the same operation brings back different result?

`Number(BigInt(1000) >> BigInt(32))`. https://stackoverflow.com/questions/2373791/bitshift-in-javascript – User863 Jul 15 '21 at 13:50

In JS all bitwise operators are signed 32bit, so >> 32 is the same as no shift – NLindros Jul 15 '21 at 13:54
