Can i assign variables as an array value?

Question

    <!doctype html>
<html lang="en">
<head>
    <title>Test</title>
    <meta charset="utf-8">

<script>
    var foodItem0 = prompt("Enter your favorite food");
    var foodItem1 = prompt("Enter your second favorite food");
    var foodItem2 = prompt("Enter your third favorite food");
    var allFood = [foodItem0,foodItem1,foodItem2];

    function favoritefood(){
        for(x=0;x>allFood.length;x++){
        var id="item"+x;
        var li=document.getElementById(id);
        li.innerHTML=allFood[x];
        }
    }
window.onload=favoritefood; 


</script>
</head>

<body>
    <h1>Top Three Favorite Food Items</h1>
    <ol>
    <li id="item0"></li>
    <li id="item1"></li>
    <li id="item3"></li>
    </ol>

</body>
</html>

If i am allowed to declare the array "allfood" like that please explain why the code is not working the list numbers are showing up but not the food that i enter in the prompts

Look in your browser console for errors. document.getElementById("item2") returns null. Your ids should be item0, item1, item2. — Matt Ball

var allFood = [foodItem0,foodItem1,foodItem2];

this is perfectly valid. This means that you are creating an array.

The code doesn't work, because of the condition in the for loop.
```
for(x=0;x>allFood.length;x++){
```
It should have been
```
for(x=0; x < allFood.length;x++){
```
After fixing that, you need to change the id of the last list item, which says item3, you might want to change it to item2.

Your "less than" symbol in your for loop is backwards. As such, your loop is exiting without running the code inside.
