Search an array for matching attribute

Question

I have an array, I need to return a restaurant\'s name, but I only know the value of its \"food\" attribute (not it\'s index number).

For example, how could I return

Answer 1

you can use ES5 some. Its pretty first by using callback

function findRestaurent(foodType) {
    var restaurant;
    restaurants.some(function (r) {
        if (r.food === id) {
            restaurant = r;
            return true;
        }
   });
  return restaurant;
}
