How to use a third-party library In Javascript
We can also use a third-party library such as Lodash or Underscore.js to remove duplicate elements from a Javascript array. The _.uniq() function returns the array which does not contain duplicate elements.
Example: In this example, we will use the _.uniq() function.
// Requiring the lodash library
const _ = require("lodash");
// Original array
let y = ([1, 2, 2, 3, 4, 3, 8, 6]);
// Use of _.uniq()
// method
let gfg = _.uniq(y);
// Printing the output
console.log(gfg);
Output:
[ 1, 2, 3, 4, 8, 6 ]
