javascript loop over three-dimensional array

var items = [[['firstName', 'Joe'], ['lastName', 'Blow'], ['age', 42], ['role', 'clerk']], [['firstName', 'Mary'], ['lastName', 'Jenkins'], ['age', 36], ['role', 'manager']]];

var result = [];
// first loop through items
items.forEach(function(item)
{
   var obj = {};
   // then loop through properties
   item.forEach(function (value)
   {
      // then set property and value
      obj[value[0]] = value[1];
   });

   // once all is done push the object
   result.push(obj);
});

console.log(result);
