How does underscore.shuffle work?

The underscore.shuffle function generates a new array containing the elements of the input array in a randomly shuffled order. The shuffle is performed using the Fisher-Yates algorithm, which iterates over the array from the end to the start, swapping the current element with a random element before it. This ensures that each element has an equal chance of being placed at any position in the shuffled array. The underscore.shuffle function takes one argument, which is the input array to be shuffled. It creates a new array and iterates over the input array using a for loop, swapping each element with a randomly selected element in the array before it. The shuffled array is then returned. Note that underscore.shuffle does not modify the input array, and instead returns a new shuffled array.

const _ = require("underscore");

const myArray = [1, 2, 3, 4, 5];
const shuffledArray = _.shuffle(myArray);

console.log(shuffledArray); // Example output: [3, 1, 5, 2, 4]

In this example, underscore.shuffle is used to shuffle the myArray array. The shuffled array is then logged to the console using console.log.
