Generates an object from the given query string or URL.
- Use `String.prototype.split()` to get the params from the given `url`.
- Use `new URLSearchParams()` to create an appropriate object and convert it to an array of key-value pairs using the spread operator (`...`).
- Use `Array.prototype.reduce()` to convert the array of key-value pairs into an object.
```js
const queryStringToObject = url =>
[...new URLSearchParams(url.split('?')[1])].reduce(
(a, [k, v]) => ((a[k] = v), a),
{}
);
```
```js
queryStringToObject('https://google.com?page=1&count=10');
// {page: '1', count: '10'}
```
