Working with Data Structures

CFScript also enables the programmer to simplify the construction of complex data structures. The tag-based structure of ColdFusion can easily become very tedious for this task. Let's say that we want to create a structure of customer billing information; we could do the following:

 <cfset customer = StructNew()>  <cfset customer.ID = FORM.CUSID>  <cfset = StructNew()>  <cfset = FORM.FirstName>  <cfset FSET = FORM.LastName>  <cfset customer.billinginfo = StructNew()>  <cfset customer.billinginfo.address = StructNew()>  <cfset customer.billinginfo.address.street = FORM.street>  <cfset =>  <cfset customer.billinginfo.address.state = FORM.state>  <cfset customer.billinginfo.address.zipcode = FORM.zipcode> 

In CFScript, we can avoid the use of the CFSET tag and just assign the values to the variable:

 <cfscript>      customer = StructNew();      customer.ID = FORM.cusid; = StructNew(); = FORM.firstname; = FORM.lastname;      customer.billinginfo = StructNew();      customer.billinginfo.address = StructNew();      customer.billinginfo.address.street = FORM.street; =;      customer.billinginfo.address.state = FORM.state;      customer.billinginfo.address.zipcode = FORM.zipcode;  <cfscript> 

The construction of arrays is very similar:

 <cfset array = ArrayNew(1)>  <cfset array[1] = "Bob">  <cfset array[2] = "Alice">  <cfset array[3] = "John">  <cfset array[4] = "Lisa"> 

In CFScript, it looks like the following:

 <cfscript>      array = ArrayNew(1);      array[1] = "Bob";      array[2] = "Alice";      array[3] = "John";      array[4] = "Lisa";  </cfscript> 

Not only is this clearer, but it also saves some typing!
