This pattern isuseful for communicating between components in the same way that you might use acallback interface in Java. Rather than repeatingthe same series of expressions each time that you need a result, you can wrapthe expressions in a function and call that function instead. Implicitly, each conditional branch returns the result of the expression on itsfinal line, so you don’t need to use a return keyword. Because the result ofall three branches is of type String, the result of the if-else expression isalso of type String. In this example, answerString is assigned an initialvalue from the result of the if-else expression.
