It is considered best practice to write ColdFusion Components and all business logic in CFScript and to use [[CFML]] only in .cfm files amongst [[HTML]].

All CFScript code must be contained within a CFScript tag pair as follows, unless it's within a pure script-based ColdFusion Component.

<source lang="cfm">

<cfscript>

ColdFusion 11, [[Railo]] 4.1+, and [[Lucee]] 4.5+ both do their best to fully support cf tags in CFScript.

<source lang="cfm">

<cfscript>
