Basics

Crystal’s syntax is heavily inspired by Ruby’s.

So it feels natural to read and easy to write, and has the added benefit of a lower learning curve for experienced Ruby devs: cat [crystal](https://) > /dev/brain.

The slick syntax makes it easy to read for humans, but it’s also fast on machines.

On the Crystal Forum you can meet humans interested in Crystal.

Press Ctr+C to end the process.
