javascript-lodashHow can I use Lodash's uniq() function to remove duplicate values from a JavaScript array?
The uniq()
function from Lodash is a helpful tool for removing duplicate values from a JavaScript array. To use it, you first need to import the function from Lodash into your project:
import uniq from 'lodash.uniq';
Then, you can call the function on the array you want to filter:
const myArray = [1, 2, 3, 4, 1, 2];
const filteredArray = uniq(myArray);
console.log(filteredArray); // [1, 2, 3, 4]
The uniq()
function will take the array as an argument and return a new array with only the unique values from the original array. In the example above, myArray
contains two duplicate values (1
and 2
), and filteredArray
is an array containing only the unique values (1
, 2
, 3
, and 4
).
It's important to note that uniq()
uses a shallow comparison for determining uniqueness, so objects with the same values will not be filtered out. If you need to filter out objects as well, you can use uniqBy()
instead.
