How to do a Key Value pair in Jquery

Question

I have the following Array X = [1,3,5] and Y = ["X", "Y", "Z"]. I need to generate output that looks like this {1:X}, {3:Y}, {5:Z}

I try this code

var X = [1,3,5];
var Y = ["X", "Y", "Z"];

var myArray = [];
    for (i = 0; i < X.length; i++) {
        myArray.push({ i : Y[i] });
    };

But that code generates a Y array without X array What jQuery code should I do to make it work?
