React.js Koans

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. No previous knowledge is required. The only thing you need to know is JavaScript (of course).

The Koans are a set of tasks to complete. Prepared tests checks if they are done correctly.

Installation

1. git clone git@github.com:arkency/reactjs_koans.git
2. npm run setup

Koans structure

• The koans directory contains the source of all the exercises. test contains the tests.
• src a contains files compiled from exercises.

You can run a webserver and see your changes live in your web browser:

1. Run command npm run start
2. Visit http://localhost:8080/

Instructions

1. Work on the code found in the exercises directory and run the tests to see if you did everything right.
2. You need to do the exercises in the given order.
3. Try to not peek at the test files! They contain spoilers.
