Do people still use jQuery? I thought the biggest advantage of this library back in the day was css selector access of DOM nodes (back when we only had getElementById, getElementsByClassName, and getElementsByTagName). This has been rolled into the Javascript document api via document.querySelector, and document.querySelectorAll. Also there are browser compatibility issues that jQuery solved but a lot of these are so…
As for why I'm not using the native DOM api's...I could, but haven't gotten around to learning that syntax since I'm very used to jquery (being specific, if I want to do things that are more complicated than selecting an element + changing its properties, the native API is more complicated). jquery is just a nice default.
