jQuery will encode and decode for you. However, you need to use a textarea tag, not a div.

var str1 = 'One & two & three';
var str2 = "One & two & three";
  
$(document).ready(function() {
   $("#encoded").text(htmlEncode(str1)); 
   $("#decoded").text(htmlDecode(str2));
});

function htmlDecode(value) {
  return $("").html(value).text();
}

function htmlEncode(value) {
  return $('<textarea/>').text(value).html();

<div id="encoded"></div>
