Understand Objects in JavaScript the best way!
Master objects to immediately improve your coding.
WHAT IS AN OBJECT?
Objects group together a set of variables and functions to create a model of something you would recognize from the real world.
For illustration, we take a hotel, whenever you think of a hotel what comes in your mind? It might be the name of the hotel, the number of rooms, or whether it has features such as a swimming pool, or a gym.
Likewise in JS to visualize better and organize code we have objects, objects can have properties and they can contain functions also and surprisingly objects can also contain objects within.
In JavaScript, there are two ways to create an object — the literal notation and the constructor function.
Creating an Object: Literal notation
This object represents a real-life hotel. It has five properties and one method. The object is in curly braces. It is stored in a variable called a hotel.
In the above code, the hotel is our object and name, rooms… are properties and available_rooms is our method, but isn’t available_rooms function? Yes, it is, but remember in objects variables used are called properties and function are called methods.
Accessing an object and dot notation
Once you have created your object you can access the properties or methods of using dot notation.
What is the dot notation?
To access a property or method of an object you use the name of the object, followed by a period, then the name of the property or method you want to access. This is called the dot notation.
In the above code, variable hotel_name contains the string “savoey”
