title: Deprecation of Javascript function unescape()
body: <p>According to <a href="http://www.w3schools.com/jsref/jsref_unescape.asp" rel="noreferrer">W3 Schools</a> the unescape() JavaScript function has been deprecated.
  The site states, </p>
  
  <blockquote>
    <p>"The unescape() function was deprecated in JavaScript version 1.5. Use
    decodeURI() or decodeURIComponent() instead."</p>
  </blockquote>
  
  <p>Should I go through and replace all instances of unescape()?</p>
  
  <p>Is the deprecation of JavaScript functions something that web developers concern themselves with and actively update their JavaScript code?</p>
  
  <p>or can I expect that most browsers will support JavaScript 1.5 in the foreseeable future? </p>
