On line 6 in the app.js file, prevent the browser's default behavior by calling the method we used on the event object.

//Problem: User when clicking on image goes to a dead end
//Solution: Create an overlay with the large image - Lightbox

  event;
  var href = $(this);

The goal here is to use the preventDefault() method on event. What this does is prevents it from doing its default behavior. Should look like this:

event.preventDefault();
