/*

|
|
* 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.
|
||
|
|
*
|
||
|
