Promises provide a cleaner and more maintainable way to handle asynchronous operations. They allow chaining with .then() and integrate naturally with async/await, making code easier to read and manage compared to nested callbacks.
Yes, questions about converting callbacks to Promises or working with asynchronous patterns are common in JavaScript interviews. They test a candidate's understanding of async programming, error handling, and modern JavaScript features.
No specialized data structure is required for this problem. The solution mainly relies on JavaScript's Promise object and function wrapping to handle asynchronous control flow.
The optimal approach is to wrap the callback-based function inside a new Promise. The Promise constructor executes the function and replaces the callback with a handler that resolves or rejects the Promise based on the callback result.
