Wyvern is a new programming language designed to help developers be highly productive when writing high-assurance applications. The first major innovation in Wyvern is type-specific languages, a feature that allows programmers to create literals of a given type (e.g.
ReScript Alternatives
ReScript is described as 'Robustly typed language that compiles to efficient and human-readable JavaScript. It comes with a lightning fast compiler toolchain that scales to any codebase size' and is a programming language in the development category. There are more than 50 alternatives to ReScript for a variety of platforms, including Linux, Mac, Windows, BSD and Web-based apps. The best ReScript alternative is Python, which is both free and Open Source. Other great apps like ReScript are Java, JavaScript, PHP and Lua.
