With JavaScript, you can define and create your own objects.

There are different ways to create objects:

Define and create a single object, using object text.

Define and create a single object through the keyword new.

Define an object constructor, and then create an object of the construction type.

In ECMAScript 5, you can also create objects through the function Object.create ().

Use the literals of the object:

This is the easiest way to create an object.

Using object text, you can define and create objects in a single statement.

The object literal refers to the name: value pair (such as age:62) in curly braces {}.

The following example creates a new JavaScript object with four properties:

Example

Var person = {firstName: "Bill", lastName: "Gates", age:62, eyeColor: "blue"}

Spaces and line breaks are not important. Object definitions can span multiple lines:

Example

Var person = {

FirstName: "Bill"

LastName: "Gates"

Age:62

EyeColor: "blue"

}

Use the JavaScript keyword new:

The following example also creates a new JavaScript object with four properties:

Example

Var person = new Object ()

Person.firstName = "Bill"

Person.lastName = "Gates"

Person.age = 50

Person.eyeColor = "blue"

The results of the above two examples are the same. No need to use new Object ().

For simplicity, readability, and execution speed, use the first creation method (object literal method).
