Recently I found a site which enable us to compare the performance of different JavaScripts that we write. This makes us choose the best code when we have several ways of doing the same thing because we can compare the performance of the script that we wrote easily.
If you are interested, go to http://jsperf.com/ to start testing.
You need to just put in “Presentation code HTML” and the required JavaScripts as test cases. Then after saving you can run the tests to check for performance.
Another feature of this site is that you can share your tests with others since you can access the tests using the shown public URL.
