 Last time, we talked about how the jQuery dollar function helps you find elements. The dollar function does not return DOM elements themselves though, but rather a wrapper that augments the element with many useful helper APIs that jQuery provides. For example, there are add class, remove class, and toggle class. And they do exactly what you think they do. They add remove or toggle CSS classes on an element. This feature is now present on the DOM directly on the class list property. This feature is sufficiently supported all the way back to IE 10. Handy! See, jQuery really did a lot for the OpenWare platform and we have some more episodes lined up on this topic, so if you find this interesting, you should subscribe. Previously, we talked about Query Selector, so why not watch that one in the meantime?
