SyntaxError: js/app.js: Unexpected token `)` (1:63)

Hi,

Any clue to pass this one?

js/app.js 
var listItems = document.querySelector('li:nth-child(#rainbow'));
var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

for(var i = 0; i < colors.length; i ++) {
  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>

Hey jc laurent,

Use ParentNode.children property to return the child elements of ul with the id of #rainbow. 

var listItems = document.querySelector('#rainbow').children;

To learn more about the property, check out this link: https://www.w3schools.com/jsref/prop_element_children.asp

Hope this helps!!
