Implement a clock that handles times without dates.
Parse and evaluate simple math word problems returning the answer as an integer.
Convert a binary number, represented as a string (e.g. '101010'), to its decimal equivalent using first principles.
Every language has its own way of doing things. CoffeeScript is no different. Our mentors will help you learn to think like a CoffeeScript developer and how to write idiomatic code in CoffeeScript. 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 CoffeeScript - they'll help you discover the things you don't know that you don't know.
