Scala is relatively young, and design decisions are aimed to address criticisms of Java.
Scala combines object-oriented and functional programming in one concise, high-level language.
Scala is statically typed and supports type inference, catching errors early.

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