Introduction

JavaScript is a powerful scripting language that every web developer should be familiar with. JavaScript has brought in many changes to the web development field. It has provided web developers with a way of making web pages more interactive. This is something most web visitors look for. If you know of validations, like checking whether a user enters correct details when filling forms, JavaScript is the best language to use for the implementation of such. It is one of the technologies of the WWW (World Wide Web). The good think with JavaScript is that it is supported by all modern web browsers. This means that you are not expected to get any special plugins to be able to run its scripts.

You can easily get started with writing and running JavaScript scripts because you only need basic elements like a text editor and a browser. Modern browsers come with the JavaScript Engine embedded; hence you dont need any other plugin to be able to run your scripts. The language also comes with many features and paradigms which you can rely on when writing your scripts. This book is an excellent guide for you on JavaScript programming. The author has discussed everything about JavaScript in a detailed manner. Enjoy reading!

To my wife and my daughter, you are the happiness of my days, and you are my truest love!

Chapter 1- JavaScript Basics

What is JavaScript?

HTML was developed for content, CSS for presentation, but JavaScript was developed for interactivity. Originally, JavaScript was developed to add interactivity (such as animations and hovers) to small web pages, but it can now be used for nearly everything including large applications, games, and servers.

JavaScript programs are known as scripts . You can write JavaScript inside the HTML of a web page and it will be executed automated when the page is being loaded. The scripts are provided in plain text and executed as they are. They dont require a compilation or a special preparation so as to run. Today, we can execute JavaScript code on a browser, server or on a device with a JavaScript Engine . Initially, JavaScript was referred to as LiveScript because it made web pages alive. This name was later changed to JavaScript.

JavaScript is an object-based scripting language which can be interpreted by all modern-day browsers. This means that all browsers come with the JavaScript Engine. This has increased the popularity of JavaScript, making it the most popular scripting language today.

Environment Setup

To write, test and run your JavaScript code, you need the following:

• Editor
• Browser

You can write your JavaScript code using even a basic text editor such as Notepad. However, it is good for you to get an advanced text editor that will provide you with features such as syntax error highlighting, auto-completion, etc. Examples of such text editors include Visual Studio, Eclipse, Aptana, etc. These can help you with speedy development.

There are also online JavaScript editors that you can use for writing your scripts. A good example of this is jsfiddle.net.

For the case of the browser, you can install any type of browser depending on your preference. Examples of such browsers include Chrome, Internet Explorer, Safari, Firefox, Opera, etc. JavaScript can work on any browser running on any OS.

JavaScript Example

There are three places where we can place our JavaScript code. We can place the code within the body, within the head tag or in an external JavaScript file. Here is our first JavaScript example:
