Missing data: null or undefined?

When using vuex-module-decorators, is it better to set the default value of a data property to null or undefined? For example:

export default class ComponentName extends Vue {
 post: BlogPost | null = null
}

or

export default class ComponentName extends Vue {
 post: BlogPost | undefined = undefined
}

Is there a definitive answer to this question?

Answer №1

When the state value cannot be determined, it is necessary to initialize it with null. Similar to wheels: number | null = null.

As mentioned in the documentation.
