Vue: delete an item from array when it is passed as a prop to a component?

vue pass props to child component
vue.js pass data from parent to child component
vue pass object as prop
vue pass all props to child
vue remove item from array
vue js pass props to child component
vue remove element from array by value
vue set remove array element

I am very new to Vue.js.

I first searched for how to do this (removing an element from an array, given just the element in the array), but all I found was references to either the delete method or calling slice on the list... which of course is relevant, but does not answer my question.

I made a fiddle here:

https://jsfiddle.net/SumNeuron/d2a9j2mh/

Ideally, I want to click delete to remove the tab and the tab pane.

Is there a way to do this without passing the list as a prop?

Is this your expectation: https://jsfiddle.net/ittus/Lost5djd/ ?

I emit event when click remove button

  methods: {
    remove: function() {
      console.log(this, this.tab)
      this.$emit('remove', this.index)
    }
  }

and listen to it on parent component

  methods: {
    onRemove(index) {
      this.groups =  [
       ...this.groups.slice(0, index),
       ...this.groups.slice(index + 1)
     ]
    }
  }

If each tab have an id, solution will be more elegant.

The simpliest way I think is to use an event on the remove button. This event carry the tab object then your parent component (your Vue application here) listen to this event and remove the tab from the list.
