CFScript is an extension of CFML on the ColdFusion platform. CFScript resembles JavaScript. Some ColdFusion developers prefer it since it has less visual and typographical overhead than ordinary CFML.

Usage

Unless it is within a pure script-based ColdFusion Component, all CFScript code must be contained within a CFScript tag pair as follows: A simple example of a function: A simple example of a component in CFScript, containing two functions: ColdFusion 11, Railo 4.1+, and Lucee 4.5+ both do their best to fully support cf tags in CFScript. While there may not be direct substitutions for all tags, it is often still possible to achieve the results of a tag in script, but via a different syntax. For example, this is how to get a query into a variable in CFSCRIPT without writing a UDF:

Syntax

Since ColdFusion 8, CFScript has supported syntax abbreviations that are common in many other programming languages, such as "++", "<=" and "+=".

Arithmetic operators

Comments
