Expressions are an important part of the ColdFusion language. Expressions are a collection of different elements, ColdFusion variables, functions, and operators. You can think of them as strings of text that consist of one or more of the following elements:
& for joining statements, + for addition, and so on)
This chapter includes many examples of expressions; for example:
#variables.my_full_name#
DateFormat(Now())
my_first_name= "Kaleigh"
When you build expressions in ColdFusion, you can include simple and complex elements; how you represent these elements determines how ColdFusion processes your application.
