==== Script syntax ====
<syntaxhighlight lang="cfs">
// arrays
arrayeach([1,2,3,4,5], function(v){
    writeOutput(v);
});

// or

for (v in [1,2,3,4,5]){
    writeOutput(v);
}

// or

// (Railo only; not supported in ColdFusion)
letters = ["a","b","c","d","e"];
letters.each(function(v){
    writeOutput(v); // abcde
});

// structs
for (k in collection){
    writeOutput(collection[k]);
}

// or

structEach(collection, function(k,v){
    writeOutput("key: #k#, value: #v#;");
});

// or
// (Railo only; not supported in ColdFusion)
collection.each(function(k,v){
    writeOutput("key: #k#, value: #v#;");
});
</syntaxhighlight>

==== Tag syntax ====
<syntaxhighlight lang="CFM">
<!--- arrays --->
<cfloop index="v" array="#['a','b','c','d','e']#">
  <cfoutput>#v#</cfoutput><!--- a b c d e  --->
</cfloop>
</syntaxhighlight>
CFML incorrectly identifies the value as "index" in this construct; the <code>index</code> variable does receive the actual value of the array element, not its index.

<syntaxhighlight lang="CFM">
<!--- structs --->
<cfloop item="k" collection="#collection#">
    <cfoutput>#collection[k]#</cfoutput>
</cfloop>
</syntaxhighlight>
