Developing ColdFusion MX Applications with CFML
Elements of CFML

Introduction

This chapter introduces and describes the basic elements of CFML. These elements make CFML a powerful tool for developing interactive web applications. Because CFML is a dynamic application development tool, it has many of the features of a programming language, including the following:

• Functions
• Expressions
• Variables and constants
• Flow-control constructs such as if-then and loops

CFML also has a "language within a language", CFScript, which enables you to use a syntax similar to JavaScript for many operations.

This chapter introduces these elements and other basic CFML entities such as data types, comments, escape characters, and reserved words.

The remainder of Part I of this book provides more detailed information on many of the basic CFML elements. The rest of this book helps you use these elements effectively in your applications.
