+### smoothScroll
+
+Smoothly scrolls the element on which it's called into the visible area of the browser window.
+
+Use `.scrollIntoView` method to scroll the element. Pass `{ behavior: 'smooth' }` to `.scrollIntoView` so it scrolls smoothly.
+
+```js
+const smoothScroll = (element) =>
+  document.querySelector(element).scrollIntoView({
+      behavior: 'smooth'
+  });
+```
+
+```js
+smoothScroll('#fooBar'); // scrolls smoothly to the element with the id of fooBar
+smoothScroll('.fooBar'); // scrolls smoothly to the element with the class of fooBar
+```
