`_.sample` function on array using JavaScript Library underscore.js

Hi Friends,

`_.sample` function on array using JavaScript Library underscore.js

`_.sample` is a utility function in Underscore.js library that allows you to retrieve a random element from an array. It provides a simple way to select a random item from a collection.

In below example, we have an array of numbers numbers. We use _.sample to retrieve a random element from the array and assign it to the variable randomNum. Each time you run the code, you will get a different random number from the array. We can also use _.sample with objects. In that case, it will return a random value from the object.

// syntax
_.sample(collection)

//example
var numbers = [1, 2, 3, 4, 5];
var randomNum = _.sample(numbers);
console.log(randomNum);
// Example output: 3 (random number selected from the array)

var obj = { name: "Alice", age: 30, city: "New York" };
var randomValue = _.sample(obj);
console.log(randomValue);
// Example output: "New York" (random selected value from the object)
