What are some real-world examples of synchronous code?

Synchronous code executes in a sequential manner, meaning each operation must complete before the next one starts. A common example is reading a file from disk. In many programming languages, the code will wait until the file is fully read before moving on to the next line.

Can you give me another example?

Sure! Another example is making a network request. In synchronous programming, the code will pause and wait for the response from the server before continuing to execute the next line.

What are the downsides of using synchronous code?

The main downside is that it can lead to performance issues, especially in applications that require high responsiveness, like web apps. If one operation takes a long time, it can block the entire application.

Are there situations where synchronous code is preferred?

Yes, synchronous code can be simpler to understand and debug, making it suitable for small scripts or tasks where performance is not a critical concern.
