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