Chapter 3. Functional Programming
You saw in Chapter 1 that pure functional programming treats everything as a value, including functions. Although F# is not a pure functional language, it does encourage you to program in the functional style; that is, it encourages you to use expressions and computations that return a result, rather than statements that result in some side effect. In this chapter, you'll survey the major language constructs of F# that support the functional programming paradigm and learn how they make it easier to program in the functional style.
