### URL parameters
Use `match()` with an appropriate regular expression to get all key-value pairs, `map()` them appropriately.
Combine all key-value pairs into a single object using `Object.assign()` and the spread operator (`...`).
Use `match()` with an appropriate regular expression to get all key-value pairs, `Array.reduce()` to map and combine them into a single object.
Pass `location.search` as the argument to apply to the current `url`.
```js
const getUrlParameters = url =>
Object.assign(...url.match(/([^?=&]+)(=([^&]*))?/g).map(m => {[f,v] = m.split('='); return {[f]:v}}));
url.match(/([^?=&]+)(=([^&]*))?/g).reduce(
(a,v) => (a[v.slice(0,v.indexOf('='))] = v.slice(v.indexOf('=')), a), {}
);
// getUrlParameters('http://url.com/page?name=Adam&surname=Smith') -> {name: 'Adam', surname: 'Smith'}
