I took this course and found it to be really comprehensive. It starts with the basics of JavaScript, like variables, operators, and loops, then gradually builds up to more advanced topics like DOM manipulation, events, and functions. One thing I really liked was the way it covered practical stuff like embedding scripts properly and optimizing website speed.

The React section was also solid. It starts with the fundamentals like components and props, then moves into hooks, state management, and even creating a small game, which made things fun and practical. There’s a ton of hands-on exercises that really helped me apply what I learned.

I also appreciated the extra sections on debugging, best practices, and deployment. There’s even content on Node.js, Vite, and making a Progressive Web App (PWA), so it’s not just about front-end stuff. It’s packed with useful shortcuts and time-saving tips too. Overall, this course is a great mix of theory and hands-on practice, especially for anyone looking to dive deep into JavaScript and React.

Having just finished the first two sections of this JavaScript course, I'm genuinely impressed and eager to share my thoughts! I started this course as a complete beginner, a bit nervous about diving into coding, especially with the ambitious goal of becoming an expert in just 30 days. But this course has laid those fears to rest with its clear, friendly, and informative teaching style.

Highl recommended, worth giving it a chance for a bit longer. Initially I wasn't convinced. Gets better and better.
