Remove attr and Remove data composed vs vanilla chained

JavaScript performance comparison

Test case created by John Bender


This tests the performance of a vanilla chain of both $.fn.removeAttr and $.fn.removeData against the performance of a composed version of the underlying $.removeAttr and $.removeData.

Preparation code

<script src=""></script>
<script src=""></script>
window.testElementCount = 10;
<script src=""></script>
Benchmark.prototype.setup = function() {
    // cache the test sets
    window.testSetDivs = $( "[data-test]" );
    // add the attribute and data to be removed
      .attr("foo", "bar")
      .attr("bing", "bang")
      .data( "baz", "bak" );
