Group array items based on variable javascript

Question

I have an array that is created dynamic from an xml document looking something like this:

myArray[0] = [1,The Melting Pot,A]
myArray[1] = [5,Mama\'s Mexican         


        

Answer 1

Good ol' ES5 Array Extras are great.

var other = {};
myArray.forEach(function(n, i, ary){
    other[n[2]] = n.slice(0,2);
});
