For example, "my " & "string" returns the string "my string". Read more – ‘Using JavaScript String Operators in ColdFusion 8’.

The basic assignment operator is equal (=), which assigns the value of its right operand to its left operand. That is, x = y assigns the value of y to x. The other assignment operators are usually shorthand for standard operations, as shown in the following table. Read more – ‘Using JavaScript Assignment Operators in ColdFusion 8’.
