On line 14 of the app.js, we want to get the anchor (the a element) from inside the listItem. Use a method to traverse and select the anchor.
//Select the navigation
var navigation = document.getElementById("navigation");
//Select all listItems from the navigation
var listItems = navigation.children;
//When a navigation link is pressed
var linkListener = function() {
console.log("Listener is clicked!");
}
var bindEventsToLinks = function(listItem) {
//Select the anchor
var anchor = listItem.onClick("a");
//Bind the linkListener to the anchor element (a)
anchor.onclick = linkListener;
}
for(var i = 0; i < listItems.length ; i++) {
bindEventsToLinks(listItems[i]);
}

var anchor = listItem.querySelector('a');
.querySelector()
returns the first element you specify that is a descendant of the element you call it on.
