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
The Emacs Lisp track on Exercism has 28 exercises to help you write better code. Discover new exercises as you progress and get engrossed in learning new concepts and improving the way you currently write.See all Emacs Lisp exercises
