What is the difference between asynchronous and synchronous iteration?

Can you explain the difference between asynchronous and synchronous iteration?

Sure! Synchronous iteration processes items one at a time, blocking the execution until each item is processed. Asynchronous iteration, on the other hand, allows for non-blocking execution, enabling multiple items to be processed concurrently.

Can you give me an example of each?

Absolutely! In synchronous iteration, you might use a simple for loop to process an array. In asynchronous iteration, you could use an async function with a for-await-of loop to handle promises as they resolve.

What are the benefits of using asynchronous iteration?

The main benefits include improved performance and responsiveness, especially in applications that handle I/O operations, as it allows other tasks to run while waiting for data.

Are there any downsides to using asynchronous iteration?

Yes, it can introduce complexity in code management and error handling, as you need to ensure that promises are properly resolved and handled.
