For small projects, this is definitely still OK. Green browsers don't really need jQuery any more, but if it's what you're comfortable using and it gets the job done, then use it.

Large projects or team projects, you will want to use something with more structure.

Some of the newer frontend frameworks are so small that it really doesn't benefit you to use jQuery even for small projects. It lacks structure and it's way too easy to start manipulating state though the dom when you could have reusable components and a decent structure with a few extra lines of code.
