Combine two arrays in JavaScript

Question

Can I merge two arrays in JavaScript like this?

these arrays:

arr1 = [\'one\',\'two\',\'three\'];
arr2 = [1,2,3];

into

<         


        

Answer 1

var arr3 = {};
for (var i = 0; i < arr1.length; i++) {
    arr3[arr1[i]] = arr2[i];
}

Please note that arr3 is not array, it is object.
