(1) JavaScript objects

JavaScript objects are data that owns properties and methods.

In JavaScript, almost all things are objects.

An object is also a variable, but an object can have more than one value.

For example:

var person = {firstName: "John", LastName: "Doe", Age:50, Eyecolor: "Blue"};

Object Properties

It can be said that a JavaScript object is a container for a variable, but a JavaScript object is generally considered a container for key-value pairs. The form is Name:value (the key is separated from the value with a colon). Key-value pairs are called object properties in the object.

Accessing Object Properties

Object properties can be accessed in two ways.

person.nameperson["name"]

Object methods

The method of the object defines a function and stores it as an object's property.

The object method is called (as a function) by adding ().

The instance accesses the FullName () method of the Person object:

1 name = Person.fullname ();

Accessing Object methods

You can create method properties in objects by using the following methods

1 methodName:function() {// actual code}

Object methods can be accessed through the following syntax

1 objectname.methodname ();
