Programming in Haskell

Foreword

• Adding recursion in the form of feedback-loops to pure combinational circuits lets us implement mutable state via flip-flops.

• True value of functional programming lies in leveraging first-class functions to achieve compositionality and equational reasoning.

Part 1 - basic concepts

• Functional programming can be viewed as a style of programming in which the basic method of computation is the application of functions to arguments.

• Functional programming language is one that supports and encourages the functional style.
