Resources for learning

I have a coworker who needs to level up her javascript in a bad way.

I’m trying to do my best to help, but I’m a) busy and b) a lousy teacher. I was hoping my fellow redditors could point me toward some resources for helping to learn that have worked for them. I’m already recommending the modern javascript tutorial from javascript.info and the latest edition of Eloquent Javascript.

What other resources would you recommend for a near beginner?

TIA!

fellow redditors? Did you copy/paste this from something you posted on reddit?
