What are best practices for using callbacks?

Callbacks are an essential part of JavaScript programming, especially in the context of asynchronous operations. Here are some best practices for using callbacks:

  • Keep Callbacks Simple: The callback function should do one thing and do it well.
  • Handle Errors Gracefully: Always include error handling in your callbacks to avoid unhandled exceptions.
  • Avoid Callback Hell: Use named functions or modularization techniques to improve readability and avoid deeply nested callbacks.
  • Consider Promises or Async/Await: For complex asynchronous flows, consider using Promises or the async/await syntax for better readability.
  • Use Consistent Naming: Name your callbacks descriptively to make your code self-documenting.
