Blob constructing

Construct Blobs (binary large objects) either using the BlobBuilder API (deprecated) or the Blob constructor.

Blob URLs

Method of creating URL handles to the specified File or Blob object.

FileReader API

Method of reading the contents of a File or Blob object into memory

View Transitions API (single-document)

Provides a mechanism for easily creating animated transitions between different DOM states, while also updating the DOM contents in a single step. This API is specific to single-document transitions, support for same-origin cross-document transitions is [being planned](https://github.com/WICG/view-transitions/blob/main/cross-doc-explainer.md).
