When should I use synchronous code in programming?

When should I use synchronous code in programming?

Synchronous code is best used when tasks need to be completed in a specific order, like reading a file before processing it.

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

Sure! If you're fetching user data from a database and then sending an email, you need the data first before sending.

What are the downsides of using synchronous code?

The main downside is that it can block the execution of other tasks, leading to performance issues, especially in I/O operations.

Are there situations where I should avoid synchronous code?

Yes, avoid it in scenarios where you need high responsiveness, like in web servers or user interfaces, to prevent freezing.
