A great exercise to enhance Javascript skills
JSchallenger is a cool tool to practice most of the primitive and non-primitive data types. It's a very helpful free Javascript resource for beginners

Seriously awesome Javascript exercises for students
I love this platform for students learning JS, as the challenges start out really easy and are skill focused. The challenges ramped up really well and aligned directly with how I was teaching. This should be an auto-include for any JS course!
