How to display an unsorted array when sorting?

Question

Vue.js

There is a code:

computed: {
        sorted() {
            const compare = (a, b) => {
                if (sortingType === '2') {
                    return b.name- a.name
                }
                if (sortingType === '3') {
                    return a.name- b.name
                }
                return 0;
            };
            return this.arr.sort(compare);
        }
    },

The user selects sorting type from the list - 2, 3 or no sorting. The problem is that when selected without sorting, computed takes an already sorted array and does not return to its original form. How to solve the problem?

Answer 1

But there is nothing to sort the array. You don't have to do this. NO NEED.
Make a copy of the array inside the computed property, and sort it.
