Also, using expressions rather than statements lets us eliminate extraneous variables, and the declarative nature of many functional solutions lets us do in a single line of code what might take five lines in the imperative style. Some object-oriented patterns can even be replaced with a straightforward application of functional language features.
Second, the functional world also has its ...
