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 variableconst 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:
Javascript
// Defining d3 contrib variableconst d3 = require('d3');let gfg = d3.permute (["Geeks", "Geeks", "for"], [0, 2, 1]);console.log(gfg); |
Output:
[ 'Geeks', 'for', 'Geeks' ]
