Why is this for loop looping infinitely?

let n = 5;

for (let a = 1, b = Math.pow(2, a); b <= n; a++) {
   console.log(b);
}

I don’t understand why b doesn’t increase as a increases. Do I have to somehow pass a to b again?

If there’s no way to make this loop work this way, can someone tell me how I could rewrite it so it works?

>Solution :

Once b is initialized, your code never changes it, so the loop condition is always true.

You could use

let n = 5;

for (b = 2; b <= n; b*=2) {
   console.log(b);
}
