javascript-lodashHow do I use Lodash to remove duplicate elements from a JavaScript array?
Using Lodash, you can remove duplicate elements from a JavaScript array by using the uniq
method. uniq
takes an array and returns a duplicate-free version of the array.
For example:
const _ = require('lodash');
const arr = [1, 1, 2, 3, 3, 4];
const result = _.uniq(arr);
console.log(result); // [1, 2, 3, 4]
The uniq
method will iterate through the array and remove any duplicate values. It will return an array with only unique values.
