While other solutions have eclipsed Jquery, it doesn’t mean it’s in any way bad. Unlike the other products here, it’s still a capable library that solves the tasks it sets out to do. It never became a bloated mess or sold out to the highest bitter.
That being said I wouldn’t really use it today. It doesn’t play that well with modern tooling, and it is extremely easy to write anti patterns into your code. I would recommend either VanillaJS, a web component library like Svelte, or React depending on what you’re trying to do.
