How to Remove Duplicates from Array Using Lodash

In this article, you will learn how to remove duplicates from an array using Lodash.

Let’s say you have an array named ‘a’ with elements ‘1, 1, 2, 2, 2, 3, 3’.

// Import Lodash library
import _ from "lodash";

var a = [1, 1, 2, 2, 2, 3, 3];

In order to remove duplicates from an array, you can use the _.sortedUniq() method.

// Import Lodash library
import _ from "lodash";

var a = [1, 1, 2, 2, 2, 3, 3];

console.log(_.sortedUniq(a));
// => [1, 2, 3]

Note: The _sortedUniq() method functions by removing duplicate elements from the supplied array.
