javascript-lodashHow do I use Lodash to get unique values in a JavaScript array?
Using Lodash, you can easily get unique values from a JavaScript array. Here is an example:
// Import Lodash
const _ = require('lodash');
// Create an array
let arr = [1, 2, 2, 3, 4, 4, 5];
// Get unique values
let unique = _.uniq(arr);
console.log(unique); // Output: [1, 2, 3, 4, 5]
The code above uses Lodash's uniq()
method to get unique values from the array arr
. The output is an array containing only the unique values: [1, 2, 3, 4, 5]
.
The uniq()
method takes an array as an argument and returns a new array with only the unique values from the original array.
Code explanation
require('lodash')
: This imports the Lodash library._.uniq(arr)
: This is the Lodash method used to get unique values from an array.console.log(unique)
: This prints the result of theuniq()
method to the console.
