Using Pre-Built Objects

JavaScript’s ability to allow developers create client side applications is through its pre-built objects. This is in line with JavaScript’s focus on Object Oriented Programming (OOP) wherein the application is rendered not by line by line interpretation but through the objects that could be launched in the client side.

For developers, the challenge of using OOP is usually based on how JavaScript would actually read the object rendered. As already indicated, JavaScript already have pre-built objects so the best way to make use of the pre-built objects is to identify them including their role in the application.

Window Object

The most popular JavaScript pre-built object is the “window object”. In fact, “window object” is not discussed as an object itself but a very important part of the Ajax and JavaScript processes.

The reason for its popularity is very simple: because JavaScript is a client side application, the only way it could be properly rendered is through window object. Without this object, developers will not have the ability to render the online application in the browser.

Complementing the popularity of window object is its perceived “smartness”. Every object and function the developer adds in window object will be automatically interpreted as a client side function. No need for developers to specify the functions of the variables and functions added in the window object.

But even though Window Object is a very essential tool in developing an Ajax or JavaScript based application, there are additional objects essential for the application to properly function.

Object Property

Simply put, the role of object property in effectively rendering client side objects is by defining its property. Through object property, developers will be able to allow JavaScript, browsers and even other websites (who might use the site as source) identify the form of data and process that should be expected. This will also aid developers who wanted to upgrade the application. Through object property, developers will be able to create a small API that might be used to call the data when the said API is integrated in other applications.

Object Method

The role of object method in JavaScript and Ajax based application is to inform the object how it should behave or react to certain commands. Object method is basically the source of information on how the window should react to user input and what form of processes it should observe.

Of course, object method will be closely working with object property. The functions and commands that will come from object method should still base its commands on object property since the information about the window object could be easily obtained through object property. Developers should be able to pair these object sources to ensure an efficient application.

Pre-built objects in JavaScript exist and they should be used thoroughly. By understanding how the major objects work in JavaScript, developers will not have a hard time creating an application according to their preferences. In fact, Object Oriented Programming (OOP) doesn’t have to be thoroughly studied before these objects could be properly implemented.
