JS Katas

This repo is not quite ready to use, currently WIP. I will remove this message once it's ready for general use

Description

A comprehensive list of Kata Descriptions as well as JS Test Scaffolding so that you can get right to practicing!

Ready to use

It provides ready scaffolding / setup for Jest and Mocha (you choose).

All you need to do is to choose which you want to use (Mocha or Jest). Just copy the mocha or jest folder to whatever kata you want to start on.

Example

I want to do the FizzBuzz kata with mocha, so I copy src/TestTemplates/mocha folder to /src/Katas/FizzBuzz
