Practical Introduction to Async Generators in JavaScript

Async generators in JavaScript combine regular generators with asynchronous programming, allowing developers to process data streams one piece at a time without loading entire datasets into memory. These functions use the `function*` syntax with `yield` statements and can handle asynchronous operations like file reading or API calls. They prove especially valuable for building modular data processing pipelines, such as ETL systems that process large CSV files row by row, preventing memory crashes and enabling real-time processing of massive datasets.
