And of course, you are correct. But many of us started with jQuery first. While I’m not one of those, I did find myself relying more and more on jQuery. Now don’t get me wrong, I love jQuery, but I realized as I became more proficient that some of the projects I was working on didn’t include a jQuery library. I could have easily added the library but I began to think about the future. What if this particular client didn’t want a jQuery library included on his site? I wanted to make sure my script would work regardless of the environment, and in order to ensure that, I eventually started writing plain old javascript.


My initial attraction to jQuery started with the ease of use of the selectors. I had a hard time memorizing the POJ selectors, and memorizing $(“element”) is easier that remembering camel humped run-on sentences. BUT I paid for it in the long run. Don’t repeat my mistakes, learn your selectors:

Select by id

Select by class

Select by query
