Iterating Array of Objects in javascript

Question

I am having an array that consists the objects with a key, value how can we iterate each object for caste and id.

[
    Object {
           


        

Answer 1

The forEach loop accepts an iterator function and, optionally, a value to use as "this" when calling that iterator function.

 var donuts = [
    { type: "Jelly", cost: 1.22 },
    { type: "Chocolate", cost: 2.45 },
    { type: "Cider", cost: 1.59 },
    { type: "Boston Cream", cost: 5.99 }
];

donuts.forEach(function(theDonut, index) {
    console.log(theDonut.type + " donuts cost $"+ theDonut.cost+ " each");
});

Subsequently it can also be broken down to this

var donuts = [
  { type: "Jelly", cost: 1.22 },
  { type: "Chocolate", cost: 2.45 },
  { type: "Cider", cost: 1.59 },
  { type: "Boston Cream", cost: 5.99 }
];


function ShowResults(donuts) {  
    console.log(donuts.type + " donuts cost $"+ donuts.cost+ " each");  
}

donuts.forEach(ShowResults);
