@ -174,13 +174,17 @@ Using `match` can make representing complex logic a lot simpler.
For example, consider wanting to add a bold mark to any text nodes that aren't already italic:
```js
Transform.setNodes(editor, {
// This path references the editor, and is expanded to a range that
// will encompass all the content of the editor.
at: [],
// This only matches text nodes that are not already italic.
match: (node, path) => Text.isText(node) && node.italic !== true,
})
Transform.setNodes(
editor,
{ bold: true },
{
// This path references the editor, and is expanded to a range that
// will encompass all the content of the editor.
at: [],
// This only matches text nodes that are not already italic.
match: (node, path) => Text.isText(node) && node.italic !== true,
}
)
```
When performing transforms, if you're ever looping over nodes and transforming them one at a time, consider seeing if `match` can solve your use case, and offload the complexity of managing loops to Slate instead.
