//My code $("#imageGallery li a").click(function(){ event.preventDefault() var href = $(this).attr( "href" ); console.log(href); )};
//Still it is working

If you have not defined anything using the name event, it will refer to the event property of the global window object.
Note that it is not good practice to rely on this being available. If you need the event object you should always pass it explicitly to your handler.

Treehouse Project ReviewerHi Prakhar,
Essentially, what your code is saying is this:
Choose the <a> that are in <li> that are in the element that has an id of "imageGallery". When the user clicks on any of these <a>; prevent the default behavior, choose the attribute "href" within the <a>, and print it to the console.
You don't always have to pass parameters to a function.
Hope this helps!
