 In practice, functionality-wise, this implementation is a drop-in replacement to GitHub's polyfill as it closely follows its implementation. Do not use this implementation if your application does not require to stream text responses.
 ## Motivation
 
-GitHub's fetch polyfill, originally designed with the intention to be used in web browsers without support for the `fetch` standard, most notably does not support the consumption of a response body as a stream.

 However, as React Native does not yet provide direct access to the underlying byte stream for responses, we either have to fallback to [XMLHttpRequest](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest) or React Native's networking API for [iOS](https://github.com/facebook/react-native/blob/v0.63.4/Libraries/Network/RCTNetworking.ios.js) and [Android](https://github.com/facebook/react-native/blob/v0.63.4/Libraries/Network/RCTNetworking.android.js). Currently, only strings can be transfered through the bridge, thus binary data has to be base64-encoded ([source](https://github.com/react-native-community/discussions-and-proposals/issues/107)) and while React Native's XHR provides [progress events](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/progress_event) to receive incremental data, it concatenates the response string as data comes in. Although [very inefficient](https://github.com/jonnyreeves/fetch-readablestream/blob/cabccb98788a0141b001e6e775fc7fce87c62081/src/defaultTransportFactory.js#L33), the response can be sliced up and each chunk encoded into its UTF-8 representation with [TextEncoder](https://developer.mozilla.org/en-US/docs/Web/API/TextEncoder).
