code: function escape(string) {
        // Reset `lastIndex` because in IE < 9 `String#replace` does not.
        string = baseToString(string);
        return (string && reHasUnescapedHtml.test(string))
          ? string.replace(reUnescapedHtml, escapeHtmlChar)
          : string;
      }
docs: Converts the characters "&", "<", ">", '"', "'", and "\`", in `string` to
  their corresponding HTML entities.
  
  **Note:** No other characters are escaped. To escape additional characters
  use a third-party library like [_he_](https://mths.be/he).
  
  Though the ">" character is escaped for symmetry, characters like
  ">" and "/" don't need escaping in HTML and have no special meaning
  unless they're part of a tag or unquoted attribute value.
  See [Mathias Bynens's article](https://mathiasbynens.be/notes/ambiguous-ampersands)
  (under "semi-related fun fact") for more details.
  
  Backticks are escaped because in Internet Explorer < 9, they can break out
  of attribute values or HTML comments. See [#59](https://html5sec.org/#59),
  [#102](https://html5sec.org/#102), [#108](https://html5sec.org/#108), and
  [#133](https://html5sec.org/#133) of the [HTML5 Security Cheatsheet](https://html5sec.org/)
  for more details.
  
  When working with HTML you should always [quote attribute values](http://wonko.com/post/html-escaping)
  to reduce XSS vectors.
