This class provides an introduction to functional programming. Functional programming is a style of programming in which computations are solely expressed in terms of applications of functions to arguments (which themselves can be functions). This style of programming has a long history in computer science, beginning with the formulation of the Lambda Calculus as a foundation for mathematics. It has become increasingly popular in recent years because it offers important advantages in designing, maintaining, and reasoning about programs in modern contexts such as web services, parallel (multi-core) programming, and distributed computing. Coursework consists of a series of programming assignments in the Racket , Java, and Haskell programming languages plus occasional and Java followed by a discussion of frameworks for reasoning about functional and imperative programs supported by written homework assignments on underlying theory.
