JavaScript courses can help you learn programming fundamentals, DOM manipulation, asynchronous programming, and event-driven development. You can build skills in debugging, working with APIs, and creating interactive web applications. Many courses introduce tools like Node.js for server-side development, React for building user interfaces, and Git for version control, showing how these skills come together in real-world projects.
