Problem Statement

Create a string variable equal to any text value. Prepend the string variable with another string literal. If your language supports any idiomatic ways to do this without referring to the variable twice in one expression, include such solutions.

To illustrate the operation, show the content of the variable.

Let's start with the solution:
