Everything looks good except that it wants your callback function in the filter() method to use an implicit return. With the curly braces and ‘return’ keyword in there, you’re making it an explicit return. Remove them and it will be implicit.

Note: I sometimes have trouble knowing when to use implicit vs explicit syntax on those callback functions. :weary:

Hi!

When you return one line code for callback function, you need implicit return and when more than one line code, you need to explicit return within callback function body {}.
