## Overview

This is a simple ReactJS front-end that allows a user to add/remove items into a basket and have the basket total automatically updated based on item price and applicable discounts.

I have:

1. used functional programming over OO

2. used javascript

3. not needed to use any functional libraries such as `lodash-fp`

4. used bootstrap + a little bit of custom styling

5. used redux

6. written clean code

7. used TDD - see the git history. As the complexity of this task was mainly in the effects of the add/remove items buttons, I mainly used integration tests to be confident about these interactions. I unit tested key functions (e.g. pricing items) to cover edge cases. I used acceptance and integration tests to ensure that important business rules are protected when changes come later.
