In many ways, learning a programming language is a lot like learning another language. 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. And, honestly, some programming is like that. Ask user name var visitor = prompt("What is your name?", “Default Name ") document.For a lot of people, the term âcomputer programmingâ conjures up visions of super-intelligent nerds hunched over keyboards, typing nearly unintelligible gibberish for hours on end. Ask user name var visitor = prompt("What is your name?", " ") User defined functions Global variables Statements that preload images for use in rollover effects Requirement analysis Goal – Audience Design Sketch the page – Site map – outline content - pseudocode Implementation Coding Support & maintenance
