copy around for later reference. Summary This chapter provided a brief overview of the basic features of JavaScript, a simple yet powerful scripting language generally hosted within Web browsers. Most of the features of the language are similar to other languages such as C or Java. Common programming constructs such as if statements, while loops, and functions are found in the language. However, JavaScript is not a simplistic language and it does contain more advanced features, such as composite data types, objects, and regular expressions. The most important part of JavaScript is its use of objects, both user-created and built-in (such as Window, navigator, and Document). Most of the book will be spent covering the use of these objects. Experienced programmers might wish to quickly skim the next few chapters, focusing on the subtle differences between JavaScript and other programming languages. However, new programmers should carefully read the next five chapters in order to get a solid foundation to build upon.
Part II: Core Language Chapter 3: Data Types and Variables Chapter 4: Operators, Expressions, and Statements Chapter 5: Functions Chapter 6: Objects Chapter 7: Array, Date, Math, and Type Related Objects Chapter 8: Regular Expressions Chapter 3: Data Types and Variables Although JavaScript was primarily intended to be used to manipulate text in the form of HTML Web pages within a browser, the data types it offers go well beyond what would be required for the task. Present in JavaScript are most—if not all—of the data types you‘d find in other modern scripting languages, as well as a robust set of features with which to manipulate them. The basic types JavaScript supports are numbers, strings, and Booleans. More complex types such as objects, arrays, and functions are also part of the language. This chapter covers in detail the basic data types and their usage. Functions and composite types, such as objects, are also briefly introduced, but a complete exposition of their capabilities is reserved for Chapters 5 and 6. Key Concepts A variable can be thought of as a container that holds data. It‘s called a ―variable‖ because the data it contains—its value—varies depending on your script. For example, you might place the total price of items a customer is buying in a variable, and then add tax to this amount, storing the result back in the variable. The type of a variable describes the nature of the data stored. For example, the type of a variable holding the value 3.14 would be number while the type of a variable holding a sentence would be string. Note that ―string‖ is programming language lingo for a sequence of characters—in other words, some text. Since you need to have some way to refer to variables, each variable is given an identifier, a name that refers to the container and allows the script to access and manipulate the data it contains. Not surprisingly, a variable‘s identifier is often referred to as its name. When scripts are run, the JavaScript interpreter (the facility within the browser that executes JavaScript) needs to allocate space in memory to store a variable‘s value. Declaring a variable is the process of telling the interpreter to get ready to store data in a new variable. In JavaScript, variables are declared using the var keyword with the name of the variable you wish to declare. For example, you might write var firstName; You can now store data in the variable known by the identifier firstName. Presumably, you‘d be storing a string here. We could then assign a value like "Thomas" to the variable. We call the string "Thomas" a literal, which describes any data appearing directly in the source code. The complete example is now var firstName; firstName = "Thomas";
