Backend Interview Question: Synchronous vs Asynchronous Programming
One frequently asked backend interview question is: "Explain the difference between synchronous and asynchronous programming, and provide an example of when you would use each in a backend application."
Synchronous Programming:
In synchronous programming, code is executed in a sequential manner. Each operation is performed one after the other, blocking further execution until the current operation is completed.
An example use case for synchronous programming in a backend application is when you need to read data from a file synchronously before proceeding with the next operation that depends on that data.
Asynchronous Programming:
In asynchronous programming, code can continue to execute without waiting for the completion of a particular operation. This allows multiple tasks to be performed concurrently.
An example use case for asynchronous programming in a backend application is when making network requests to external APIs. By making these requests asynchronously, the application can continue to handle other tasks while waiting for the responses.
