- Explain the use of callbacks: I would explain that callbacks are functions that are passed as arguments to other functions, and they are executed when a particular event occurs. I would also mention that callbacks can lead to callback hell, which can be hard to manage.
- Discuss Promises: I would talk about promises and how they are a better alternative to callbacks. I would explain that promises are objects that represent a value that may not be available yet, but will be resolved in the future.
- Give an example: Finally, I would give an example of how I have used asynchronous programming in a project, and how it helped me to improve the performance of the application.
