How is it possible that the output of the code is zero since we have the value of x set to 1?

Question

var arr = [1,2,3,4];
var x = 1;
for(var i = 0; i < arr.length;i++) {
x*=i;
}
alert(x);

Answer 1

Okay, i in the for loop isn't a representation of the array's elements, but the array's indexes. Indexes start from 0, not from 1, so you'll first be multiplying by 0

Answer 2

Airree I'm sorry but I still don't understand

Answer 3

Oh okay, thanks Airree

Answer 4

This isn't an enhanced for loop, so if you look at it closely, you don't multiply by arr[i], but by i, which is 0, 1, 2, 3.
