What are the differences between synchronous and asynchronous error handling?

What are the differences between synchronous and asynchronous error handling?

Synchronous error handling occurs in a blocking manner, where the code execution waits for the error handling to complete. In contrast, asynchronous error handling allows the program to continue executing while handling errors, often using callbacks or promises.

Can you give me an example of each?

Sure! In synchronous error handling, you might use a try-catch block that halts execution until the error is handled. In asynchronous error handling, you might use a promise with a .catch() method that allows other code to run while waiting for the promise to resolve.

Which one is better to use?

It depends on the context. Synchronous error handling is simpler and easier to understand, but it can block the execution flow. Asynchronous error handling is more efficient in non-blocking scenarios, especially in I/O operations.

Are there any drawbacks to asynchronous error handling?

Yes, asynchronous error handling can lead to more complex code and make debugging harder. It can also introduce issues like callback hell if not managed properly.
