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].

Let's change our initialization so we can count by odd numbers. Instructions

Push the odd numbers from 1 through 9 to myArray using a for loop.

// Example
var ourArray = [];

for (var i = 0; i < 10; i += 2) {
  ourArray.push(i);
}

// Setup
var myArray = [];

// Only change code below this line.
for (var i = 1; i < 10; i += 2) {
  myArray.push(i);
}
