Question

I have this array,

var arr1 = [19, 1, 1, 1, 1];

and another array,

var arr2 = ["Default", "Dynamic", "Assessment", "Risk", "Privacy"];

What I would like is to merge them somehow such that it would look something like this,

var merged_array = [ ["Default", 19], ["Dynamic", 1], ["Assessment", 1], ["Risk", 3], ["Privacy", 2] ];

how would I do that? I tried join but I did not achieve what I wanted. Thanks in advance!

Answer 1

Using a for loop:

var merged_array = new Array(arr1.length);
for (var i = 0; i < arr1.length; i++) {
  merged_array[i] = new Array(arr2[i], arr1[i]);
}

This assumes arr1 and arr2 have the same length.
