Lodash _.sample() Method

Lodash's _.sample() method randomly selects and returns a single element from a collection (array, object, or string). If the collection is empty, it returns `undefined`. It's useful for retrieving random items efficiently.

Syntax:

_.sample(collection);

Parameters:

• collection: This parameter holds the collection to sample.

Return Value: This method is used to return the random element.

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

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.

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.
