Question

setTimeout(function log() {
console.log(i);
}, 1000);
}

Answer 1

Change `var` to `let`

for( let i = 0; i < 3; i++ )
// rest of code

I don't know how to explain that though : )

I recall this question been asked before, but maybe the previous threads had irrelevant title or tag, I just can't find them using search terms I figured related.
