Once a program is compiled, you can run it on your computer, and because a compiled program has been converted directly to instructions a computer understands, it will run faster than a program written with a scripting language.

Compiling is the process of creating a file that will run on a computer by translating the code a programmer writes into instructions that a computer can understand. Most of the programs running on your computer are written using languages that are compiled. I’ve heard this term used for other languages like PHP and ColdFusion as well. JavaScript is called a scripting language. So with a little bit of JavaScript knowledge and the help of jQuery, you’ll be creating sophisticated, interactive websites in no time.įREQUENTLY ASKED QUESTION: Compiled vs. jQuery makes complex JavaScript programming easier… much easier. In addition, this book isn’t just about JavaScript-it’s also about jQuery, the world’s most popular JavaScript library. (And if you do have programming experience, this book will teach you JavaScript’s idiosyncrasies and the unique concepts involved in programming for web browsers.) But don’t worry: If you’ve 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. You’ll make plenty of mistakes as you start to learn to program-that’s just the nature of programming.Īt first, you’ll probably find JavaScript programming frustrating-you’ll spend a lot of your time tracking down errors you made when typing the script. Likewise, a simple typo or even a missing punctuation mark can prevent a JavaScript program from working, or trigger an error in a web browser. When learning to speak a new language, you quickly realize that placing an accent on the wrong syllable can make a word unintelligible. You’ll need to memorize the words and rules of the JavaScript language (or at least keep this book handy as a reference).

You need to learn new words, new punctuation, and understand how to put them together so you can communicate successfully.Įvery programming language has its own set of keywords and characters, and its own set of rules for putting those words and characters together-the language’s syntax. 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, you’ll learn how to approach a programming task so you’ll know exactly what you want to do before you start adding JavaScript to a web page. Throughout this book, you’ll learn fundamental programming concepts that apply whether you’re 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 aren’t 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 that’s well beyond the average mortal. And, honestly, some programming is like that. When this error occurs, the data in the program may be lost.For a lot of people, the term “computer programming” conjures up visions of super-intelligent nerds hunched over keyboards, typing nearly unintelligible gibberish for hours on end. Hardware error is nothing but a malfunction of a hardware device, which is physically present in the computer.Ī fatal error is an error that causes a code to abort.

The logic error will produce wrong output that may not be immediately identifiable by a programmer.Īn error that occurs on the source code of a program is referred as syntax error because the computer programs strictly follow the syntax rules and if the code fails to prove its language syntax format, then the compiler will throw an error.

The problem with the logic error is that it will not make the program to terminate or crash.Once the program is in an executable form, test the program whether it has any logic error.

In this scenario, the program will work correctly but will produce output with errors.Logic error is called as a bug, which will make a program to operate with fault, in which the program may respond differently and can produce unexpected results.
