By completing the quizzes, you will sharpen your coding logic, debug effectively, and gain the confidence needed for both personal projects and technical interviews.

• DOM Manipulation & Events: query selectors, event listeners, event propagation

• Asynchronous JavaScript: callbacks, promises, async/await, fetch API, error handling

• Problem-Solving & Interview Prep: tricky questions, performance considerations, coding challenges

Whether you are a beginner looking to solidify your fundamentals or an intermediate developer preparing for job interviews, this course will push your JavaScript knowledge to the next level.
