Question

Ever heard of vars hoisting? Please look it up out

of curiosity. Short answer: declared inside the loop, the var is still gets declared as if it was at the beginning of the holding function. So, no need for declaration inside the for loop. That’s es5. Things gets a bit different in es6 grounds. Look up “scopes es6”
