Find the bug in this animation loop.
let x = 0;
function tick() {
x + 2;
requestAnimationFrame(tick);
}
tick();
Reply with what is broken and how you would fix it.
x + 2; is just an expression you throw away, so x never changes and stays 0 forever.
Fix is to actually assign it: x += 2; (or x = x + 2;) inside tick() so it updates each frame.
