2 Functional programming techniques for concurrency

This chapter covers

  • Solving complex problems by composing simple solutions
  • Simplifying functional programming with closures
  • Improving program performance with functional techniques
  • Using lazy evaluation

Writing code in functional programming can make you feel like the driver of fast car, speeding along without the need to know how the underlying mechanics work. In chapter 1, you learned that taking an FP approach to writing concurrent applications better answers the challenges in writing those applications than, for example, an object-oriented approach does. Key concepts, such as immutable variables and purity, in any FP language mean that while writing concurrent applications remains ...
