Answer
Async iterators allow sequential handling of asynchronous data streams using for-await-of. Useful for paginated APIs or real-time feeds. Provides clear and controlled async flow.
Quick Answer
Async iteration with for await...of processes streams of data: async function processStream(stream) { for await (const chunk of stream) { process(chunk) } }. Node.js Readable streams implement async iteration natively. For paginated APIs: yield pages from an async generator and consume with for await. Cleaner than recursive Promise chains for sequential async data.
