## Iterate Odd Numbers With a For Loop

<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds  -->
Here’s the example:

```javascript
var ourArray = [];

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

// Setup
var myArray = [];

// Only change code below this line.
```
 Here’s a solution:
 After string `// Only change code below this line.` we add `for` loop. You need to copy loop from the top:
 
 ```javascript
for (var i = 0; i < 10; i += 2) {
  ourArray.push(i);
}
 ```
 And change `initialization` `var i = 0` to `var i = 1`, also you need change name of the array `ourArray` to `myArray`:
 
  ```javascript
for (var i = 1; i < 10; i += 2) {
  myArray.push(i);
}
 ```
 
  Here’s a full solution:
  
  ```javascript
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);
}
```
