Roc Has a Free API: The Functional Language Designed for Application Development

Haskell is powerful but impractical. Elm is practical but limited. Roc aims to be both — a fast functional language for real apps. What Is Roc? Roc is a functional programming language focused on speed, friendliness, and practicality. Created by Richard Feldman (Elm core team), it compiles to machine code and interops with any language through platforms. app [main] { pf: platform "https://github.com/roc-lang/basic-cli/..." } import pf.Stdout main = Stdout.line! "Hello from Roc!" Why Roc 1. Fast — Compiles to LLVM machine code. No garbage collector pauses — uses reference counting. 2. No runtime exceptions — The type system eliminates null, undefined, and unhandled errors: # Result type for operations that can fail parseAge : Str -> Result U32 [InvalidAge] parseAge = \input -> when Str.toU32 input is Ok age if age > 0 && age < 150 -> Ok age _ -> Err InvalidAge 3. Platform model — Roc doesn't have a runtime. It plugs into "platforms" that provide I/O: basic-cli — command-line apps basic-
