Not sure what i am doing wrong here. Is event.target == ‘.student-list’? I get a little confused with event.target still

Your click event is technically triggered whenever you click on the ul, but I think it will also trigger if you click on its children

You are near. Inside of your click handler, use jQuery ($ <- jQuery selector) to 'select' event.target, then call the hide() method on your selection. Hope this help.

You have it pretty close, but some things are out of order. First line is correct, so now we move to the second line.

hide() is the method the Challenge is asking you to "call". When attaching a method, there will also be a dot operator. Since methods are functions that means you also need to call it. How do we call a function--we add parentheses. Like this: hide()

The other error you made was omitting the jQuery selector before (event.target). For a deeper understanding of event.target I would recommend the MDN docs.

$('.student-list:hidden').on('click', function(){
  this.show();  
});
