+### Bottom visible

+Returns `true` if bottom of the page is visible. It adds `scrollY` to
+the height of the visible portion of the page (`clientHeight`) and
+compares it to `pageHeight` to see if bottom of the page is visible.
+
+```js
+const bottomVisible = () => {
+  const scrollY = window.scrollY;
+  const visibleHeight = document.documentElement.clientHeight;
+  const pageHeight = document.documentElement.scrollHeight;
+  const bottomOfPage = visibleHeight + scrollY >= pageHeight;
+
+  return bottomOfPage || pageHeight < visibleHeight;
+}

 ### Capitalize first letter of every word
 
 Use `replace()` to match the first character of each word and `toUpperCase()` to capitalize it.

 ### Bottom visible
 
-Returns `true` if bottom of the page is visible. It adds `scrollY` to
-the height of the visible portion of the page (`clientHeight`) and
-compares it to `pageHeight` to see if bottom of the page is visible.
+Use `scrollY`, `scrollHeight` and `clientHeight` to determine if the bottom of the page is visible.
 
 ```js
-const bottomVisible = () => {
-  const scrollY = window.scrollY;
-  const visibleHeight = document.documentElement.clientHeight;
-  const pageHeight = document.documentElement.scrollHeight;
-  const bottomOfPage = visibleHeight + scrollY >= pageHeight;
-
-  return bottomOfPage || pageHeight < visibleHeight;
-}
+const bottomVisible = _ => 
+  document.documentElement.clientHeight + window.scrollY >= document.documentElement.scrollHeight || document.documentElement.clientHeight;
+// bottomVisible() -> true
 ```
