If you want to learn React.js you came to the right place. We prepared a set of practical exercises that will help you learn React.js from square one. The only thing you need to know is JavaScript. Here we are using ECMAScript 2015 standard.
The Koans are a set of tasks to complete. Prepared tests checks if they are done correctly.
Make sure you have Node.js and Python 2 installed.
