jQuery makes complex JavaScript programming easier⦠much easier. In addition, this book isnât just about JavaScriptâitâs also about jQuery, the worldâs most popular JavaScript library. (And if you do have programming experience, this book will teach you JavaScriptâs idiosyncrasies and the unique concepts involved in programming for web browsers.) But donât worry: If youâve tried to learn JavaScript in the past and gave up because you thought it was too hard, this book will help you get past the hurdles that often trip up folks new to programming. Also, you might find some of the concepts related to programming a bit hard to follow at first. Youâll make plenty of mistakes as you start to learn to programâthatâs just the nature of programming.Īt first, youâll probably find JavaScript programming frustratingâyouâll spend a lot of your time tracking down errors you made when typing the script.

An average JavaScript program is sprinkled with symbols (, () !=) and full of unfamiliar words ( var, null, else if). Many web designers are immediately struck by the strange symbols and words used in JavaScript. More importantly, youâll learn how to approach a programming task so youâll know exactly what you want to do before you start adding JavaScript to a web page. Throughout this book, youâll learn fundamental programming concepts that apply whether youâre writing JavaScript, ActionScript, or even writing a desktop program using C++. Still, JavaScript is more complex than either HTML or CSS, and programming often is a foreign world to web designers so one goal of this book is to help you think more like a programmer. But many programming concepts arenât difficult to grasp, and as programming languages go, JavaScript is a good first language for someone new to programming. ![]() ![]() Programming can seem like complex magic thatâs well beyond the average mortal.
