How to use uniq method In Lodash
In this approach, we will use Lodash’s uniq function, which returns a new array with unique elements from the input array, removing duplicates while maintaining the order of elements.
Syntax:
_.uniq(array)
Example: The below example uses the uniq function to remove duplicate elements from an array using Lodash.
const _ = require('lodash');
let arr =
["apple", "mango", "apple",
"orange", "mango", "mango"];
let res = _.uniq(arr);
console.log(res);
Output:
[ 'apple', 'mango', 'orange' ]
