Value

import { Value } from 'slate'

A Value is the top-level representation of data in Slate, containing both a Document and a Selection. It's what you need to pass into the Slate <Editor> to render something onto the page.

All changes to the document and selection are also performed through the value object, so that they can stay in sync, and be propagated to its internal history of undo/redo value.

For convenience, in addition to changes, many of the selection and document properties are exposed as proxies on the Value object.
