Vue 2 - How to set default type of array in props

ES6 variety For an Array

props: {
  arr: {
    type: Array,
    default: () => []
  }
}

...And for an Object

props: {
  obj: {
    type: Object,
    default: () => ({
      param: value,
      param2: value,
    })
  }
}

I created example: jsFiddle, that might can help you, and yes... you can return the default value as a array:

ES6

props: {
    items: {
        type: Array,
        default: () => []
    }
}
