Imagine a language with the syntax of Ruby but an order of magnitude faster. That’s the short pitch for Crystal, a statically typed compiled language with a syntax that is directly inspired by Ruby. In fact, it is so close to Ruby in some respects that some Ruby code can run unmodified on Crystal. But Crystal is not a language that should be viewed in the shadow of Ruby; it’s a compelling choice for anyone who cares about both the aesthetics of code and performance.
James Thompson takes you through the history and the current state of Crystal and explains how to use it effectively and where it needs your help. You’ll also discover how to create a Crystal Shard (library) and explore popular tools and Shards available right now.
James Thompson is a principal software engineer at Mavenlink, where he is committed to helping engineering teams become more deliberate in how they build software through developing strong learning cultures, principled engineering practices, and holistic architectural thinking. He has worked with web technologies since 2003.
