+Generates an object from the given query string or URL.
+
+- Use `String.prototype.split()` to get the params from the given `url`.
+- Use the `URLSearchParams` constructor 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'}
+```
