Objects in Javascript

Objects in Javascript are collection of properties. An object stores data in the form of key value pair. These are non-primitive type structure, because we can store multiple types (both primitive and non-primitive) data in any object.
While storing data in any object, for our reference, we associate that data to a key name. These keys are known as the object’s property. Object properties can be of any type
For example, a car can have many properties like make, model, year etc. And, we can represent a car or any other entity using an object like below:
var car = {
make: 'Audi',
model: 'A3',
year: 2018
};
