jQuery provided a lot of quality-of-life functionality that is now part of the native Javascript language/runtime on modern browsers. The most famous likely being the selector querying functionality, and the event management (and I'm sure others I am not thinking of). jQuery still works, but under the hood it's just proxying those native methods, so you might as well just use those native methods directly.
