### Code Explanation:
Explain solution here and add any relevant links
* Assign **temp** to `str.split('')`, which creates an array containing each individual character in the passed in string.
* Pass each character in the newly created array into a `switch()` statement.
* Replace the HTML entities with their corresponding HTML entity string (i.e. `'&'` becomes `'&'` in line 51)
* `temp.join('')` converts the array of characters into a string to be returned.

* **str** is assigned to a new version of **str** that will contain the original string with all HTML entities converted
* The **first parameters** in `replace()` contains a regular expression that matches all instances of each HTML entity in **str**
* Replace all those instances with the corresponding HTML strings given in the **second parameter** of `replace()`
* Finally, the new **str** is returned
