Lambda Calculus for Babies: Retarded Babies
Lambda Calculus forms the fundamentals of functional programming. If it can be described as a function, it can be described in the lambda calculus and consequently written in Haskell
Alpha equivalence
- Variable name doesn't matter
Beta reduction
Meat of Lambda calculus.
Ex:
(ƛx.x)2 (ƛ[x:=2x]) 2 (ƛz.zz)(ƛy.yy) (ƛ[z:=(ƛ
