toJSON()​

toJSON(): Record<string, any>

Called by built in JSON.stringify (see https://javascript.info/json) Properties are read-only as they are not deep-cloned (not necessary for stringification).

Returns​

Inherited from​

BaseNode . toJSON

See​

toMutableJSON - use to return a mutable JSON instead

Source​
