Why is learning JavaScript still important in the era of AI tools like ChatGPT?

Despite AI tools like ChatGPT being able to generate code, understanding JavaScript remains crucial. Developers still need to review, refine, and tweak AI-generated code to ensure it works properly for specific projects, similar to how you wouldn't sign a legal contract without lawyer review. JavaScript is ubiquitous, powering over 98% of websites and used in frontend, backend, and mobile development. For those looking to advance their skills, TypeScript offers a perfect upgrade by adding static typing that catches bugs early, improves maintainability, and enhances productivity on larger projects.
