How to sort an array alphabetically

String.localeCompare()

If you're working with a relatively small array, you could use localeCompare().

const arr = [
  {
    name: "Orange"
  },
  {
    name: "Banana"
  },
  {
    name: "Carrot"
  },
  {
    name: "Apple"
  }
];

// [{"name":"Apple"},{"name":"Banana"},{"name":"Carrot"},{"name":"Orange"}]
console.log(arr.sort((a, b) => a.name.localeCompare(b.name)));

Intl.Collator()

If you're working with a large array, I would recommend using Intl.Collator() for performance reasons.

const arr = [
  {
    name: "Orange"
  },
  {
    name: "Banana"
  },
  {
    name: "Carrot"
  },
  {
    name: "Apple"
  }
];
const collator = new Intl.Collator();

// [{"name":"Apple"},{"name":"Banana"},{"name":"Carrot"},{"name":"Orange"}]
console.log(arr.sort((a, b) => collator.compare(a.name, b.name)));
