jQuery each vs JS forEach

Benchmark created by John on

Description

This is just a test I did to see which is faster, the JS version or the jQuery version. Both are Javascript based, but I just wanted to see whether jQuery got away with something when it comes down to performance and memory management

Preparation HTML

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<script>
  // Setup collection
  var collection = [];
  for (var i = 0; i < 200; i++) {
    collection.push({
      index: i,
      data: 'Index element ' + i
    });
  }
</script>
