| # Slate React Hooks | |
| #### `useComposing(): boolean` | |
| Get the current `composing` state of the editor. It deals with `compositionstart`, `compositionupdate`, `compositionend` events. | |
| Composition events are triggered by typing (composing) with a language that uses a composition character (e.g. Chinese, Japanese, Korean, etc.) [example](https://en.wikipedia.org/wiki/Input_method#/media/File:Typing_%EC%9E%88%EC%8A%B5%EB%8B%88%EB%8B%A4_in_Dubeolsik_keyboard_layout.gif). | |
| #### `useElement(): Element` | |
| Get the current element object. Re-renders whenever the element or any of its descendants changes. | |
| #### `useElementIf(): Element | null` | |
| The same as `useElement()` but returns `null` instead of throwing an error when not inside an element. | |
| #### `useFocused(): boolean` | |
| Get the current `focused` state of the editor. | |
| #### `useReadOnly(): boolean` | |
| Get the current `readOnly` state of the editor. | |
| #### `useSelected(): boolean` | |
| Get the current `selected` state of an element. An element is selected if `editor.selection` exists and overlaps any part of the element. | |
| #### `useSlate(): Editor` | |
| Get the current editor object. Re-renders whenever changes occur in the editor. | |
| #### `useSlateStatic(): Editor` | |
| Get the current editor object from the React context. A version of useSlate that does not re-render the context. Previously called `useEditor`. | |
| #### `useSlateSelection(): (BaseRange & { placeholder?: string | undefined; onPlaceholderResize?: ((node: HTMLElement | null) => void) | undefined }) | null` | |
| Get the current editor selection. Only re-renders when the selection changes. | |
| #### `useSlateSelector<T>(selector: (editor: Editor) => T, equalityFn?: (a: T, b: T) => boolean): T` | |
| Use redux style selectors to prevent re-rendering on every keystroke. | |
| Bear in mind re-rendering can only prevented if the returned value is a value type or for reference types (e.g. objects and arrays) add a custom equality function. | |
| If `selector` is memoized using `useCallback`, then it will only be called when it or the editor state changes. Otherwise, `selector` will be called every time the component renders. | |
| Example: | |
| ```typescript | |
| const isSelectionActive = useSlateSelector(editor => Boolean(editor.selection)) | |
| ``` | |
