/* | ||
* Converts HTML entity codes in a string to the characters they represent. | ||
* | ||
* Example: | ||
* `decodeHTMLEntities('Beets & carrots');` | ||
* will return "Beets & carrots". | ||
* | ||
* The regex makes sure we only replace the HTML entities in the string. | ||
* For example, the regex would match "<" as well as ":". | ||
* The decoding works by setting the innerHTML of a dummy element and then | ||
* retrieving the innerText. Per the spec, innerText is a property that | ||
* represents the "rendered" text content of an element. | ||
* | ||
* See: | ||
* https://developer.mozilla.org/en-US/docs/Web/API/Node/innerText | ||
* https://developer.mozilla.org/en-US/docs/Glossary/Entity | ||
