  xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
      document.getElementById("demo").innerHTML = xhttp.responseText;
    }
  };
  xhttp.open("GET", "ajax_info.txt", true);
  xhttp.send();

Tools For Angular

February 13, 2016

Different useful tools to develop AngularJS apps. Notepad++ simply the best free open source text editor. Sublime Text 3 Chrome developer tool – out of the box (just right click then Inspect Element). AngularJS Batarang Chrome extension: useful to debug our application. JetBrains Webstorm IDE: according to me the best JavaScript editor.
