    Excellent course for JavaScript interview preparation. The instructor explains concepts like closures, event loop, promises, async/await, prototypes, and the “this” keyword in a very clear and practical way. The questions are real interview-level and very helpful for frontend roles like React, Angular, Vue, and Next.js. Perfect for anyone looking to strengthen JS fundamentals and crack tech interviews. I Highly recommended!
