Some weeks ago, a colleague laughed at me when I asked: "btw, do we use jQuery somewhere in our web app?" - he said, its no more a thing today.

Is that true?

(Im out of webdev for years)

jQuery is certainly still used in a lot of production apps and they still release updates.

But most new web apps will use a flavor of React.

I bet half the devs who say 'we don't use it', probably have it on their site and don't realize it.
