Get mentored the Groovy way

Every language has its own way of doing things. Groovy is no different. Our mentors will help you learn to think like a Groovy developer and how to write idiomatic code in Groovy. 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 Groovy - they'll help you discover the things you don't know that you don't know.
