+Creates an object containing the parameters of the current URL.
+
+- Use `String.prototype.match()` with an appropriate regular expression to get all key-value pairs.
+- Use `Array.prototype.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 =>
+  (url.match(/([^?=&]+)(=([^&]*))/g) || []).reduce(
+    (a, v) => (
+      (a[v.slice(0, v.indexOf('='))] = v.slice(v.indexOf('=') + 1)), a
+    ),
+    {}
+  );
+```
+
+```js
+getURLParameters('google.com'); // {}
+getURLParameters('http://url.com/page?name=Adam&surname=Smith');
+// {name: 'Adam', surname: 'Smith'}
+```
