How to use the PHP bitwise AND operator with Javascript

Question

I am trying to do what PHP does with the & AND operator but in javascript. An example would be the following:

// PHP
$a = '100110100011111000100110';
$b = '111111111111111111111110';

echo $a & $b //100110100011111000100110

Well, it is the result that I must achieve in javascript ... trying it from the beginning would be ..

// JS
const a = 100110100011111000100110;
const b = 111111111111111111111110;

console.log(a & b) //536870912

Honestly, I know very little about binary, I have tried some functions using bitwise XOR and reviewed the topic right here in StackOverflow but the truth is confused.

Answer 1

Well thanks to the comments of those who responded, and looking and entering the topic, I reviewed the documentation of both languages and then what I did was divide the strings, and do the and - & to each pair of their position and the result it was similar to php.

here as I did.

const a = '100110100011111000100110';
const b = '111111111111111111111110';

function andBin (one, two) {
  const _a = one.split('')
  const _b = two.split('')
  let result = ''

  _a.map((e, i) => {
    result += Number(e) & Number(_b[i])
  })

  return result

}

andBin(a, b) // 100110100011111000100110

ready. resolved, thank you all very much.
