A versatile web framework and library for building client-side and server-side web applications

Hyperapp is a functional JavaScript framework for building hypertext applications. It centers on a state management library and a virtual DOM system that creates in-memory interface representations to apply efficient updates to the browser screen via diffing. The framework avoids templates and JSX, instead utilizing function composition and dedicated tag wrappers to generate HTML structures and SVG elements. It implements a unidirectional data flow where a central state object is managed through transformation functions. The system covers declarative UI rendering and functional web interfaci

TEA for Bucklescript

Roc is a statically typed, functional programming language built around immutable-by-default semantics, exhaustive pattern matching on tag unions, and a type system that combines optional explicit annotations with full compile-time type inference. Its core identity centers on correctness and expressiveness, using tagged unions for error handling with a question-mark operator for early error propagation, and a trailing-bang naming convention that makes side-effect boundaries syntactically visible at every call site. The language distinguishes itself through a platform-based I/O abstraction tha
