+### 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`.
+
+```js
+var getUrlParameters = url =>
+  Object.assign(...url.match(/([^?=&]+)(=([^&]*))?/g).map(m => {[f,v] = m.split('='); return {[f]:v}}));
+```
