🍭 reswitcher

Functional switch case for redux reducers.

Switch cases are slow, or that's what they said.

They also say, it doesn't fit in the functional paradigm.

It's also not Immutable.

It uses break, which is anti-functional.

...bla, bla, bla...

This is a super fast and lightweight (3 lines of code) recomposition of switch statement for functional code, which makes this statement easy and fast to read.

Usage

Install it as dependency:

npm i reswitcher --save

or

yarn add reswitcher

And now...! Feel free to use it as your reducer.

import reswitcher from 'reswitcher';

const counter = (state = 0, action) =>
  reswitcher({
    'RESET': 0,
    'INCREMENT': () => state + 1,
    'DECREMENT': () => state -1
  })(state)(action.type)
