Becoming good at jQuery is reasonably quick and easy. If you have a use case for it, Yes! Why not? (ex: legacy stuff)

Is it a valuable skill? Well, probably not! But not because of React or Angular, only because being good at jQuery is easy. Which makes it a less valuable skill and that is why I said if you have a use case for it.

Not to mention, a big part of jQuery success was the short learning curve. While simplicity is its strong point, it is also what makes it less valuable as a skill.

Unlike back-end technologies, front-end technologies have a shorter lifespan. Because of all the design evolutions, redesigning, and front-end optimizations and refactoring which is more accessible and less resource hungry for many businesses. So keep that in mind that probably you are not going to use jQuery in any customer-facing new project.
