When using Vue decorator notation, I typically write it like this:
@Prop({ type: Object || null, default: null })
However, I noticed in the Vue documentation that they use array notation:
@Prop({ type: [ Object, null ], default: null })
Is there a specific reason for using || in the notation?
For further information on this topic, refer to Logical OR (||). If you use null || Object, you will receive Object, as Boolean(null) evaluates to false. With your approach, you will also receive Object because Boolean(Object) results in true. However, a better way of utilizing it would be:
@Prop({ type: Object, default: null })
Avoid using it solely in an array format like ([Object]).
