Example 1:

HTML

<script src="https://d3js.org/d3.v4.min.js"></script>

<script>
    // Initialising a array
    var Array = [10, 20, 30, 40, 50];

    // Calling the d3.quantile() function
    A = d3.quantile(Array, 0);
    B = d3.quantile(Array, 0.25);
    C = d3.quantile(Array, 0.5);
    D = d3.quantile(Array, 0.75);
    E = d3.quantile(Array, 1);

    // Getting the shuffled elements
    console.log(A);
    console.log(B);
    console.log(C);
    console.log(D);
    console.log(E);
</script>

Output:

10
20
