When should I use synchronous calls in programming?

When should I use synchronous calls in programming?

Synchronous calls are best used when you need to ensure that a task completes before moving on to the next one.

Can you give me an example of when that would be necessary?

Sure! For instance, if you're fetching user data that is required for the next operation, a synchronous call ensures you have that data before proceeding.

Are there any downsides to using synchronous calls?

Yes, they can block the execution of other tasks, leading to performance issues, especially in I/O operations.

So, when should I avoid them?

Avoid synchronous calls in scenarios where you need to maintain responsiveness, like in user interfaces or when handling multiple requests.
