Iterate array object using foreach in javascript

Question

Below is an array of objects which I need to print in the below expected format only using forEach in javascript

var donuts = [
    { type: "Dairy Milk", cost: 1.22 },//object
    { type: "Kit Kat", cost: 2.45 },
    { type: "Milky Bar", cost: 1.59 }
];

Expected output:

Dairy Milk cost $1.22 each
Kit Kat cost $2.45 each
Milky Bar cost $1.59 each

How do I do that?

donuts.forEach(d => console.log(`${d.type} cost $${d.cost} each`))

Every array in JavaScript has a method called forEach that basically calls a function for each of the elements of your array. Inside this function you can call console.log.

The example above uses the arrow function notation, which apart from a few differences is basically just a more concise way to declare a function.

Also in this example you can notice the use of string templates, denoted by the text inside backticks, where you can use placehoders ${} to place dynamic content in your string.

While this code may answer the question, it would be better to include some context, explaining how it works and when to use it. Code-only answers are not useful in the long run. – Maximilian Peters Mar 25 '18 at 20:00

You could do:

yourArray.forEach(function(element){
    console.log(element.type + ‘ costs $’ + element.cost + ‘ each’);
});
