Reserved words
In addition to the names of ColdFusion functions and words reserved by ColdFusion
expressions (such as NOT, AND, IS, and so on), the following words are reserved in
CFScript. Do not use these words as variables or identifiers in your scripting code:
Differences from JavaScript
CFScript is similar to JavaScript, however, there are some key differences in CFScript:
•
It uses ColdFusion expressions, which are neither a subset nor a superset of
JavaScript expressions. For example, there is no < operator in CFScript.
•
It does not have user-defined variable declarations.
•
It is case-insensitive.
•
All statements end in a semicolon, and line breaks in the code are ignored.
•
Assignments are statements, not expressions.
•
Some implicit objects are not available, such as Window and Document.
Note
CFScript is not directly exportable to JavaScript. Only a limited subset of JavaScript
can run inside CFScript.
