How to generate all the binary options of N bits in JavaScript

Answer 1

function generateAllBinaryOptions(N) {
    let binary = [];

    const total_bits = parseInt("1".repeat(N), 2) + 1;

    for (let i = 0; i < total_bits; i++) {
        binary.push(i.toString(2).padStart(N, '0'));
  	}

  return binary;
}


const N = 4;
console.log(generateAllBinaryOptions(N));
