Example 1: In this example, we can see that by using d3.permute() method, we are able to get the single array after permutation having values specified in the source array and using keys for the permutation.

Javascript

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

const gfg = d3.permute([1, 2, 3, 4], [3, 2, 1, 0]);

console.log(gfg);

Output:

[ 4, 3, 2, 1 ]

Example 2:

const d3 = require('d3');

let gfg = d3.permute
    (["Geeks", "Geeks", "for"], [0, 2, 1]);

console.log(gfg);

Output:
