Look at the QuerySelector apis to do stuff that you always thought needed jQuery.


Look at the QuerySelector apis to do stuff that you always thought needed jQuery. We will also look at how the common apis work and what it takes to start programming with them. Note: This is not to state jQuery is irrelevant, but a step to make you use jQuery at instances where it is really needed


JavaScript programming experience, experience working with jQuery dom querying operations

    @Amit - Agree. I will try and fit some of those pieces in to the talk.
    @Kamal - I almost do not use jQuery for DOM querying anymore, complex or not. This talk is more about looking at what’s possible directly with open standards without having to mandatorily rely on jQuery.

    I am not sure if selector’s api is enough food for the entire session. It would be great if you can also include new utilities like classList, matchesSelector, insertAdjacentHTML, contains and other related things which are also frequent reasons why newbies use jQuery.

    Have you used this to build something complex? or you find it interesting and want to share it with the rest of us?
