Suggestion to add an additional "Helpful Link" to the "Convert HTML Entities" challenge

Challenge Convert HTML Entities.

Before I submit a PR, I’d like to get feedback on adding an additional link to reference on this challenge.

I might be wrong but I think this is the first exposure users have to regular expressions in the track so I think it would be helpful to also include a reference to .replace() which makes solving this challenge much more manageable for new coders.

Example solution:

function convert(str) {

  // The list of chars to convert
  var charHTMLlist = {
    "&" : "&",
    "<" : "&lt;",
    ">" : "&gt;",
    '"' : "&quot;",
    "'" : "&apos;"
  };

  // Char replacement function triggered when a match is found
  function charHTMLmapper(ch){
    return charHTMLlist[ch];
  }

  // Returns a new string with the encode matches
  return str.replace(/[&"'<>]/g, charHTMLmapper);

}

// returns "Dolce &​amp; Gabbana"
convert("Dolce & Gabbana");
