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