The World of JavaScript Makes The Internet A More Interactive Place

JavaScript

The programming world, is indeed a different type, of a world, when you compare it, with other worlds, in the universe.

However, there is definitely a heaven and a hell, which can fill very real, when you experience one or the other.

In general, you have to be able to think clearly about, the purpose of your application, to write your code, and before you even begin to write your code, you need to have a clear picture, of what you want to do.

If you don’t think about what you will be coding, then you can forget it.

You won’t be able to write a useful application, because you don’t have a purpose in mind.

In today’s article, we will be discussing JavaScript, and how important, this language is for website development.

As a, cross-platform, object-oriented scripting language; JavaScript is a small and lightweight language.

JavaScript is able to provide, programmatic control over the object of its environment, when it is used inside a host environment, such as a web browser, by connecting to them.

A standard library of objects, such as Array, Date and Math is always part of JavaScript.

As well as a core set of language elements; such as operators, control structures and statements, are also part of the JavaScript programming language.

Objects in the client side and server side can be supplemented, to JavaScript, to extend its core for a variety of purposes.

The ability to control a browser and its Document Object Model (DOM), is part of the main purpose of JavaScript, which is able to accomplish this, thanks to its extension to the core of JavaScript.

The client-side supplied object, to JavaScript, allows it, to give front-end website developers, the ability to control, the browser.

If a designer for example, would like to place elements on an HTML form and respond, to user events, such as mouse clicks, form input and page navigation; then a designer can use client-side extensions, in order to accomplish this task.

The Server-side can also be extended, at the core of JavaScript, by supplying objects, which are relevant to running JavaScript on a server.

JavaScript can be extended on the server-side, for example, to allow an application to communicate with a database, to provide, continuity of information from one invocation to another of the application, or perform file manipulation on a server.

JavaScript resides inside HTML documents, and can provide levels of interactivity, to web pages that are not achievable with simple HTML.

JavaScript is used, most times in combination with HTML, CSS and AJAX, so that you can accomplish, the task, which you have in front of you.

Another thing you have to remember, is that not all browsers, will respond the same way; therefore, you need to be able, to write your JavaScript code, in all of the browsers, which exit today.

JavaScript is able to run, in most modern browsers though, so you don’t have to worry about, too much of these changes.

The difference, can be painful, to overcome though, because JavaScript is an object oriented, and a procedural programming language as well.

It can be used to control web pages on the client side of the browser, server-side programs, and even mobile applications.
