Train Now

Start training on this collection. Each time you skip or complete a kata you will be taken to the next kata in the series. Once you cycle through the items in the collection you will revert back to your normal training routine.

Description

All these kata have been designed to allow mastering the use of higher-order functions. In JavaScript this includes methods like: forEach, filter, map, reduce, some, every, find, findIndex. Other approaches to solving the katas are of course possible.
