### escapeHTML
Escapes a string for use in HTML.
Use `String.replace()` with a regex that matches the characters that need to be escaped, using a callback function to replace each character instance with its associated escaped character using a dictionary (object).
```js
const escapeHTML = str =>
str.replace(
/[&<>'"]/g,
tag =>
({
'&': '&amp;',
'<': '&lt;',
'>': '&gt;',
"'": '&#39;',
'"': '&quot;'
}[tag] || tag)
);
```

### unescapeHTML
