Introduction
This book contains proven steps and strategies on how to code in JavaScript. I have included in the book step-by-step programming techniques in JavaScript so that you can learn them properly. JavaScript is a scripted language. You will see a lot of script embedded in HTML tags. As JavaScript cannot work alone, I deemed it fit to embed it in HTML so that when you want to run it, it works well in web browsers.
If you want to practice what you have learned, you can open up a code editor, copy the code, and paste it in to check out the results. Also, you can simply load up the page to the web browser to see the results directly on the web page. Embedded scripts are in ready-to-work form. The best method to learn the scripts by heart and then edit them to customize them so that you can learn faster and in a fun way.
Whether you are making websites or are a student who aspires to become a web developer, or are planning to build a website for your own business, this book is the best literature you may come across on the market. Once you have gone through the first couple of chapters, you will be in the right mindset to move on and learn the complex topics. The best method is to go slow at first and pace yourself as the concepts become clearer.
Chapter One: An Introduction to JavaScript
JavaScript is an interpreted language. The definition of the language is broader than the word interpreted. You can define it as a procedural language that is weakly typed, based on prototypes, and is dynamic and imperative. JavaScript is developed and implemented in the form of a client-side programming language. It is a part of the web browser and is seen as something that can facilitate developers for the implementation of dynamic features and creation and integration of user interface on the web pages. You may find some implementation of JavaScript on the server-side as well. However, the popularity of the JavaScript programming language is largely based on its applications on the client-side. You may see applications of JavaScript outside of web applications as well. For example, you may find them being used as a way to add some interactivity to the desktop widgets and to documents in PDF format.
JavaScript was initially designed in the same mold as the C language was designed, but it also takes some Java programming language names. You should not mistake Java for JavaScript because the two are inherently different. They have different purposes and semantics as well.
The Developer of JavaScript
Brendan Each developed JavaScript initially with the name Mocha. The name was changed later on to LiveScript. Late on, it was changed again to JavaScript. The name confused some people, and it gave the impression that the new language, namely JavaScript, was an offshoot of Java. People thought that the new programing language was part of Netscape's marketing strategy to gain the much-needed prestige in the world of new programming languages.
The next year, Microsoft introduced a similar client-side language integrated into their famous Internet Explorer 3.0 browser. It named the language JScript to get away with brand problems. The term as it sounds and looks was perceived as so much similar to JavaScript; however, where it differed was that it could not be made 100% compatible with the specifications of ECMA.
