How do I convert an integer in JavaScript to a 32bits?

Question

I have some numbers (base 10) that I want to convert to a 32 bits(base 2), I have tried a lot of things, I found out the >>> operator, but apparently it only converts negative numbers to a base 10 the equivalent of the 32 bits, instead of base 2

const number = 3

const bitNumber = 1 >>> 0

console.log(bitNumber) /// 1

JavaScript doesn't have a base 2 number type (as far as I know). — evolutionxbox, Sep 13 '22 at 00:04

All numbers can be expressed in whatever base you want, as strings. — Heretic Monkey, Sep 13 '22 at 00:07

The numbers are always stored as bits internally. It’s console.log that converts them to a string, and the string conversion uses decimal by default.

You can pass a base to Number.prototype.toString:

console.log(bitNumber.toString(2));

and display as many bit positions as you want:

console.log(bitNumber.toString(2).padStart(32, '0'));

Thanks for the answer, it worked nicely. I was thinking that JS had some method that already transformed in 32 bit positions numbers, but padStart is the way – Felipe Tomazetti Sep 14 '22 at 12:07
