# very simple but i can't solve [Refactor Using a Loop]

The code below logs all of the even numbers from 2 to 24 to the JavaScript console. However, there's a lot of redundant code here. Re-write this using a loop.

script.js
```for (var i=2; i<=24;i+=1 ){
document.write(i++);
}
```
index.html
```<!DOCTYPE html>
<html>
<meta charset="utf-8">
<title>JavaScript Loops</title>
<body>
<script src="script.js"></script>
</body>
</html>
```

You can check for every i from 2 to 24 if the remainder of dividing i by 2 is equals to 0, if it does that means that i is an even number. You can do that with '%' operator which returns the remainder of a division.

```for( var i = 2; i <= 24; i += 1){
if(i % 2 === 0){
console.log(i);
}
}
```

Or you can simply increase i in your loop by 2 instead of 1

```for(var i =2; i <=24; i +=2){
console.log(i);
}
```

thanks so much Vladut for the help and explaination. its now clear to me now. my brain is very slow. Can i follow you in twitter? :)

You're welcome, I'm so glad I could help! If you want to follow me on twitter you can find me @AstVLD

You're told to print all even numbers below 24. First off, we declare a for loop. Then, we declare a variable called i and assign a value of 2, this variable will be the counter and give a condition for the loop to run, in this case, print the value below or equal to 24. Then, increment it by 2 and inside the loop, log the value to the console. The values will be the same as the redundant code as before.

```for (var i = 2; i <= 24; i += 2) {
console.log(i);
}
```
