Angular vs. jQuery vs. Native vs. Native (New School)

JavaScript performance comparison

Revision 8 of this test case created

Info

Comparison study for how an MVC framework vs. jQuery vs. native code vs. querySelector performs while rendering a list populated from an array. We're doing a study trying to determine the best JavaScript approach to an app running on an ARM board, so we want to get a sense of what we're sacrificing in native js vs. newer native js vs. jquery-only vs. angular.js scenarios.

Preparation code

<!-- Jquery -->
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<h1>jQuery:</h1>
<div id="jq_test"></div>

<script type="text/javascript">
var jqEl = $('#jq_test');
var children = '';
var jqPush = function (data) {
  children += '<span>' + data + '</span>';
}
var jqRender = function () {
  jqEl.append(children);
  //jqEl.append('<span>' + data + '</span>');
}
var jqClear = function () {
  jqEl.empty();
  children = '';
// not sure if we need to do more to prevent memory leak - probably doesn't matter
}
</script>

<!-- Angular -->
<div ng-app>
  <h1>Angular:</h1>
  <div ng-controller="Ctrl" id="angList"><span ng-repeat="item in data">{{item}}</span></div>
</div>

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.3/angular.min.js"></script>

<script type="text/javascript">
  var Ctrl = function($scope){
    $scope.data = [];
  }
 
  angular.element(document).ready(function() {
    var angScope = $('#angList').scope();
   
    window.angularClear = function(){
      angScope.data.splice(0, angScope.data.length);
     // angScope.$digest();
    };
    window.angularPush = function(data){
      angScope.data.push(data);
     // angScope.$digest();
    };
    window.angularApply = function(data){
      angScope.$apply();
    };
  });
</script>

<!-- Native -->
<h1>Native (getElementById):</h1>
<div id="native_test"></div>

<script type="text/javascript">
var nativeEl = document.getElementById('native_test');
var nativeChildren = '';
var nativePush = function (data) {
  var el = '<span>' + data + '</span>';
  nativeChildren += el;
}
var nativeRender = function () {
  nativeEl.innerHTML = nativeChildren;
}
var nativeClear = function () {
  while (nativeEl.hasChildNodes()) {
    nativeEl.removeChild(nativeEl.lastChild);
  }
  nativeChildren = null;
  nativeChildren = '';
}


</script>


<!-- Native New -->
<h1>New Native (querySelector):</h1>
<div id="native_test_new"></div>

<script type="text/javascript">
var newNativeEl = document.querySelector('#native_test_new');
var newNativeChildren = '';
var newNativePush = function (data) {
  var el = '<span>' + data + '</span>';
  newNativeChildren += el;
}
var newNativeRender = function () {
  newNativeEl.innerHTML = newNativeChildren;
}
var newNativeClear = function () {
  while (newNativeEl.hasChildNodes()) {
    newNativeEl.removeChild(newNativeEl.lastChild);
  }
  newNativeChildren = null;
  newNativeChildren = '';
}


</script>
