Let's dive into the world of JavaScript microbenchmarks on MeasureThat.net.

**Benchmark Definition Json**

The benchmark definition json contains information about the test case and its script preparation code. In this case, we have two individual test cases: "Parent 2" and "Closest 2". The script preparation code is empty, which means that no specific setup or initialization is required for these tests.

**Tested Options**

The two test cases are comparing the performance of `denna.parent()` and `denna.closest('li')` methods.

*   **denna.parent()**: This method returns a reference to the parent element of an element.
*   **denna.closest('li')**: This method searches for the closest ancestor that matches the specified selector.

**Options Compared**

The options being compared are:

1.  `denna.parent()`: Returns a reference to the parent element, which can be used to traverse the DOM tree upwards.
2.  `denna.closest('li')`: Searches for the closest ancestor that matches the 'li' selector and returns it.

**Browser and Device Information**

The latest benchmark result includes information about the browser and device being tested:

*   **Browser**: Chrome 83
*   **Device Platform**: Desktop
*   **Operating System**: Mac OS X 10.12.6

**Performance Results**

The performance results show the number of executions per second for each test case:

*   **Parent 2**: 17862.1875 executions/second
*   **Closest 2**: 14767.310546875 executions/second

These results indicate that `denna.parent()` is faster than `denna.closest('li')` on this specific browser and device configuration.

**JavaScript Functions Used**

Both test cases utilize the jQuery library, which is included in the benchmark definition json:

*   `$ = function(jQuery) { ... };`
*   `denna = $( "#filterType" );`

These lines of code set up a jQuery object named "denna" and initialize it with an element that has the id "filterType".

**Conclusion**

In summary, MeasureThat.net is testing the performance of two JavaScript methods: `denna.parent()` and `denna.closest('li')`. The results indicate that `denna.parent()` is faster than `denna.closest('li')` on this specific browser and device configuration.
