Example 1: In this example, we are getting a random value from an integer array by the use of the lodash _.sample() method.

javascript

// Requiring the lodash library
const _ = require("lodash");

// Original array
let array1 = ([3, 6, 9, 12]);

// Use of _.sample() method
let gfg = _.sample(array1);

// Printing original Array
console.log("original array1: ", array1)

// Printing the output
console.log(gfg);

Output:

original array1: [ 3, 6, 9, 12 ]
12

Example 2: In this example, we are getting a random value from an string array by the use of the lodash _.sample() method.

javascript

// Requiring the lodash library
const _ = require("lodash");

// Original array
let array1 = (['mon', 'tue', 'wed',
    'thu', 'fri', 'sat', 'sun']);

// Use of _.sample() method
let gfg = _.sample(array1);

// Printing original Array
console.log("original array1: ", array1)

// Printing the output
console.log(gfg);

Output:

original array1: [ 'mon', 'tue', 'wed', 'thu', 'fri', 'sat', 'sun']
mon

Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
