In which cases is it advisable to use synchronous operations?

Synchronous operations are advisable to use in cases where:

• Sequential data processing is required, and the result of the current operation is needed for the next.
• The operation executes quickly and does not block the main thread, such as simple calculations or access to local data.
• It is important to keep the code simple without introducing asynchrony, especially in small scripts or utilities.
• The runtime environment does not support asynchrony or its use is redundant.

For example, reading a small file in a script where subsequent logic depends on the file's contents can be performed synchronously for simplicity and predictability.
