Simple helper method for working with JSON

forEachInObj.js

var foods = {
  'italian' : 'pizza',
  'mexican' : 'burrito', 
  'japanese' : 'sushi'
};

// Normal way of iterating 
for (var category in foods) {
  console.log(foods[category], ' is a type of ', category, ' food.');
}

// Simple helper function for iterating over each key/value pair
function forEachInObj (object, callback) {
  for (var key in object) {
    callback(key, object[key]); 
  }
}

// This is a little simplier to read and write
forEachInObj(foods, function (category, dish) {
  console.log(dish, ' is a type of ', category, 'food.');
});
