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 (...). Pass location.search as the argument to apply to the current url.

const getUrlParameters = url =>
  Object.assign(...url.match(/([^?=&]+)(=([^&]*))?/g).map(m => {[f,v] = m.split('='); return {[f]:v}}));
// getUrlParameters('http://url.com/page?name=Adam&surname=Smith') -> {name: 'Adam', surname: 'Smith'}
