The challenge was to prepend a checkbox to a li. In an jQuery $().each loop this references the li element (In this case).

Inorder to prepend a element you have to define it: 

var checkbox = '<input type="checkbox"/>';

And prepend it via jQuery:

$(this).prepend(checkbox);

Do not forget $() inorder to use jQuery

So I tried that.. $('.favorite-things li').each(function() { // Write code here var checkbox = '<input type="checkbox"/>'; $(this).prepend(checkbox); });

and it told me AST unexpected node call pass expression: Literal..

Hi, Brian

Sorry I don't know what this error means(maybe a bug in workspaces because I can not find any explanation in the web), but if you pass the string directly to the prepend method like this

$(this).prepend('<input type="checkbox"/>');

Hope this works Know this works
