match('x', {
  x: 2,
  y: 1
}, 100); // => 2

match('none', {
  x: 2,
  y: 1
}, 0); // => 0

match('none-without-default', {
  x: 2,
  y: 1

Personally, i wrote this module for usage with redux and es6, it fits pretty nice, but you can use it wherever you want to:

export default (state = {}, action) => match(action.type, {
  [FETCH_POSTS]: () => ({...state, posts: action.posts})
}, state);
