fetchResult

The `fetchResult` method is a function available in JavaScript, primarily used within the context of asynchronous operations involving the Fetch API. It is designed to retrieve the response body of a fetch request as a stream of data, allowing for incremental processing without loading the entire response into memory at once.

When making HTTP requests with the Fetch API, the `fetchResult` method is not directly called by developers; instead, it is an internal method used by the browser to handle responses. However, developers can leverage similar concepts by using the `Response` object's built-in methods, such as `json()`, `text()`, or `blob()`, which internally utilize streaming techniques to process data efficiently. The `fetchResult` concept aligns with the broader idea of streaming responses, which is particularly useful for large files or real-time data streams.

The method is part of the underlying implementation of the Fetch API, ensuring that responses are processed in a memory-efficient manner. This is especially beneficial for handling large datasets or continuous data feeds, where loading everything at once could cause performance issues or memory exhaustion. By streaming data incrementally, applications can process and display information as it arrives, improving responsiveness and scalability.

Developers should focus on the higher-level methods provided by the Fetch API, such as `response.body` or `response.arrayBuffer()`, which abstract away the complexities of streaming and allow for straightforward consumption of response data. These methods enable developers to work with data streams without needing to directly interact with the `fetchResult` mechanism.
