Iterate Odd Numbers With a For Loop
For loops don't have to iterate one at a time. By changing our final-expression
, we can count by even numbers.
We'll start at i = 0
and loop while i < 10
. We'll increment i
by 2 each loop with i += 2
.
var ourArray = [];
for(var i = 0; i < 10; i += 2) {
ourArray.push(i);
}
ourArray will now contain [0,2,4,6,8]
