Every language has its own way of doing things. Emacs Lisp is no different. Our mentors will help you learn to think like a Emacs Lisp developer and how to write idiomatic code in Emacs Lisp. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Emacs Lisp - they'll help you discover the things you don't know that you don't know.Learn more about mentoring
