Example 1: In this example, we can see that by using d3.shuffler() method, we are able to get the random shuffle function which we can use it to shuffle the elements in an array by using this method.

Javascript

// Defining d3 contrib variable
var d3 = require('d3');

const random = d3.randomLcg(0.67019185816);
var gfg = d3.shuffler(random);

console.log(gfg([0, 1, 2, 3, 4]));

Output:

[ 3, 0, 4, 2, 1 ]

Example 2:

Javascript

// Defining d3 contrib variable
var d3 = require('d3');

const random = d3.randomLcg(0.5816);
var gfg = d3.shuffler(random);

console.log(gfg([5, 6, -1, 3, 4]));

Output:

[3, 5, 6, -1, 4]

Example 3:

Javascript

// Defining d3 contrib variable
var d3 = require('d3');

for(var i = 0.1; i <= 0.5; i+=0.1) {
    var random = d3.randomLcg(i);
    var gfg = d3.shuffler(random);

    console.log(gfg([-5, 6, -1, 3, -4]));
}

Output:

[ -4, 6, -5, -1, 3 ]
[ -1, 3, -5, -4, 6 ]
[ -5, -4, 6, -1, 3 ]
[ -1, 3, -4, -5, 6 ]
[ 6, -1, -5, -4, 3 ]
