The for loop cycles over list items and applies a color to each item using the values stored in the colors array. For ex

The for loop cycles over list items and applies a color to each item using the values stored in the colors array. For example, the first color in the array ( #C2272D) is applied to the first list item, the second color (#F8931F) to the second list item, and so on. Complete the code by setting the variable listItems to refer to a collection. The collection should contain all list items in the <ul> element with the ID of rainbow.

Does anyone know what's the problem?

js/app.js 
var listItems;
var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];
let children = node.children;


for(var i = 0; i < colors.length; i ++) {
    listItems = document.querySelectorAll(".rainbow"); 
    listItems[i].style.color = colors[i];
index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Rainbow!</title>
  </head>
  <body>
    <ul id="rainbow">
      <li>This should be red</li>
      <li>This should be orange</li>
      <li>This should be yellow</li>
      <li>This should be green</li>
      <li>This should be blue</li>
      <li>This should be indigo</li>
      <li>This should be violet</li>
    </ul>
    <script src="js/app.js"></script>
  </body>
</html>

You are selecting the element with class rainbow which is the <ul> itself you need to select the <li> items , and will be good to do it in the beginning where you have variable named listItems

var listItems = document.querySelectorAll("li");
