Frontend Looks Fine with AI, But Should I Still Learn the Basics Properly?

So far, I was involved in frontend development, and now I started to use some AI tools to create UI components, layouts, animations, and also make my work more productive. Frontend side is fine and I manage to build quite nice interface thanks to AI.

But still, sometimes, I'm afraid that my base knowledge is not strong enough, and I feel gaps in such areas as JavaScript principles, React basics, optimization techniques, and frontend architecture as a whole. So sometimes I understand the code provided by AI, but most often, I just change things a little bit, not being aware of its logic.

Thus, my question is:

Is it reasonable to proceed with developing my projects using AI while learning at the same time or should I first thoroughly learn frontend concepts?

Ultimately, I want to be an experienced frontend developer, not just copying AI-generated code. I would highly appreciate your opinion regarding the issue as I'm aspiring for becoming a professional.

Thanks in advance!
