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
Record<string, any>
See
toMutableJSON - use to return a mutable JSON instead

Defined in
toMutableJSON
▸ toMutableJSON(): Record<string, any>
Converts the object to a JSON representation. Properties can be safely modified as a deep clone of the properties are created.
Returns
Record<string, any>
- The JSON representation of the object.
