Software complexity grows not just from problems we solve, but from flexibility languages give us. TypeLang explores enforcing functional principles and explicit effects through constraints—making illegal states unrepresentable and side effects visible in type signatures.
Side effects scattered everywhere make code hard to test and reason about. Flix's algebraic effect system brings discipline—declare what functions can do, verify at compile time, handle effects in one place.
Building a pure TypeScript Mermaid renderer that works server-side - no browser, no DOM simulation, just functional patterns and smart type system usage.
How Effect-TS separates business logic from technical plumbing - error handling, async operations, and dependency management that doesn't obscure what your code actually does.
Callback hell plagues functional programming—deeply nested code that obscures logic. Gleam's `use` syntax solves this elegantly with one simple construct. Here's what makes it interesting and how to apply similar patterns in TypeScript.
Real functional programming benefits in TypeScript without fp-ts or complex abstractions - just pure functions, explicit errors, and smart use of the type system.
