XHR limitations and drawbacks:

• more complicated API, request and response concepts are mixed together.
• lacks streaming, whole response is going to buffer in memory, not available for binary data

Fetch API features and pros:

1. more pleasant simpler API. Has Request and Response abstractions, can be used separately (for example in ServiceWorkers). Based on Promises.
2. supports streaming, response.body is ReadableStream, you can read data chunk by chunk without buffering, available for binary data. Can access partial content while response is being received.
3. has cache control support (default, no-store, reload, no-cache, force-cache, only-if-cached)
