JAVASCRIPT A Beginner’s Guide to Learning the Basics of JavaScript Programming By James Patrick Introduction I want to thank you and congratulate you for downloading the book, “Javascript Programming !” This book contains proven steps and strategies that even beginners can use in order to code from scratch. Even better, intermediate systems and tutorials are included so that those who are already familiar with Javascript can amp up their game and use JavaScript in conjunction with more advanced tools and systems. This book includes a short introduction to the programming language so that you’ll know exactly what to expect. You will then be guided through the basics, including variables, identifiers and statements. You will also get oriented regarding javascript syntax. Several guides and samples are also included so that you’ll see exactly how certain keywords and data will appear on webpages. Don’t worry because to learn Javascript, there is no need for you to pay for other third- party software and tools. All you need is Notepad, or TextEdit if you are using a Mac computer. When you move on to the intermediate stages though, it would be better for you to use a source code editor that offer HTML and CSS support, such as Notepad ++. Thanks again for downloading this book. I hope you enjoy it!
