Correct: `Array.from()` (it’s a static method) Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method) This patch uses the common `#` syntax to denote `.prototype.`.

### getURLParameters
|
|
|
|
Returns an object containing the parameters of the current URL.
|
|
|
|
Use `String.match()` with an appropriate regular expression to get all key-value pairs, `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('http://url.com/page?name=Adam&surname=Smith'); // {name: 'Adam', surname: 'Smith'}
|
|
getURLParameters('google.com'); // {}
|
|
```
