A quest through the beautiful strangeness of functional programming.

λ

Types

Every value knows what it is. The type system is your first collaborator, catching errors before they exist.

λ

Functions

Pure transformations from input to output. No side effects, no surprises -- just mathematical clarity.

λ

Patterns

Deconstruct data with elegance. Pattern matching turns complex structures into simple, readable cases.

λ

Monads

Friendly containers that sequence computation. They carry context -- and they are not as scary as they sound.

λ

Effects

IO lives at the edge. Pure functions remain pure while effects are tracked, controlled, and composed.

λ

Composition

Small functions combine into larger ones. The whole is built from parts, and the parts remain independent.

The Pipeline

input map filter fold result

Data flows through pure transformations, each function a waypoint on the journey from input to insight.

Every type tells a story. Every function is a chapter. Start yours.
