Lodash provides a convenient way to remove duplicates from an array in JavaScript. Here is an example of how it can be done:
const _ = require('lodash');
const array = [1, 2, 3, 4, 4, 5, 5];
const uniqueArray = _.uniq(array);
console.log(uniqueArray); // Output: [1, 2, 3, 4, 5]
The _.uniq()
method takes an array as an argument and returns an array with only unique values. It uses a strict equality check (===
) to determine the uniqueness of each element.
Code explanation
const _ = require('lodash');

method to remove duplicates from thearray
and store the result inuniqueArray
.console.log(uniqueArray);
