String Concatenation

[Other Languages] 
ASP Classic:  "String Concatenation" & or +

Although you can use either a & or a + to concatenate values, my preference is to use a + because more languages use it. However, if you use & then some type conversions are done for you. If you use + you will sometimes have to cast a value to concatenate it. For example, you will have to use CStr to cast a number to a string if you use the + operator as a concatenation operator.

Syntax Example:
Dim FirstName
Dim LastName
 
FirstName  = "Mike"
LastName  = "Prestwood"
 
Response.Write "Full name: " & FirstName & " " + LastName
 
Response.Write "2+2=" + CStr(2+2)
JavaScript:  "String Concatenation" +

To concatenate two strings, a string to an integer, or a string to a floating point number, use the + operator. JavaScript performs implicit casting when concatenating a string and a number. For example, to convert a floating point number to a string just concatenate an empty string to the number as in "" + 3.2.

Syntax Example:
