Question

I’m using javascript and trying to sync two arrays so that both arrays have the same index location.

    var array1 = ["word1","word2","word3","word4","word5"];
    var array2 = [1,2,3,4,5];

    array2.sort(function(){ return Math.random() -.5});

This scrambles array2 into something like [2,3,1,5,4]

Now I need array1 to get the same order: ["word2", "word3", "word1", "word 5", "word4"]

How can I do this?

Answer 1

Something like this should be a pretty simple way to do it:

//assume array1 is like in your example and 
//array2 is the result of the randomization
var result = [];
for(var i = 0; i < array2.length; i++) {
    result[i] = array1[array2[i]];
}
