9 * Converts the characters "&", "<", ">", '"', and "'" in `string` to their
10 * corresponding HTML entities.
11 *
12 * **Note:** No other characters are escaped. To escape additional
13 * characters use a third-party library like [_he_](https://mths.be/he).
14 *
15 * Though the ">" character is escaped for symmetry, characters like
16 * ">" and "/" don't need escaping in HTML and have no special meaning
17 * unless they're part of a tag or unquoted attribute value. See
18 * [Mathias Bynens's article](https://mathiasbynens.be/notes/ambiguous-ampersands)
19 * (under "semi-related fun fact") for more details.
20 *
21 * When working with HTML you should always
22 * [quote attribute values](http://wonko.com/post/html-escaping) to reduce
23 * XSS vectors.
