Improvements Made: 1. Context Handling: Fixed the issue with the forEach method by using an arrow function to preserve the context of this. 2. Performance Optimization in poll(): Simplified the logic to replace the top element with the last element and directly called heapifyDown() only if the heap is not empty after removing the top. 3. Cleaner heapifyDown() Logic: Streamlined the logic for determining the larger child index. This makes it clearer and avoids unnecessary comparisons. 4. Destructuring in swap(): Used array destructuring for swapping elements, which is more concise and readable. 5. Optional Return Value in peek(): Updated the peek() method to return undefined if the heap is empty, enhancing clarity. Overall, these changes improve the maintainability, readability, and performance of the code while retaining the core functionality of the max heap data structure. Thank you .

There was a problem hiding this comment.
Why do we explicitly check? !this.isEmpty() here at line no 27 as we are returning undefined if this.isEmpty() is true.
So the lines 25 to 29 will execute only if !this.isEmpty() is true. This check is redundant here.
