[Link] Basics of Lambda Calculus

Post icon  Posted 07 February 2014 - 07:41 AM

This is more of a computer science-y topic, but lambda calculus is an important foundation of functional programming that I figured it would still be a good link here.


λ-calculus performs computation using mathematical functions. The notation used is called Lambda Abstraction. Many procedural languages (which are not based on λ-calculus) treat data variables and functions differently. For example, we can't assign a function to another function like we usually do with variables [2](function pointers are different!). On the other hand, functional programming languages (for example Haskel) which are based on λ-calculus treat data variables and functions as same. Of course, there are other differences but those are not relevant for this discussion.
