ReScript is a robustly typed programming language that compiles to efficient, human-readable JavaScript, with a lightning-fast compiler toolchain and built-in build system. It offers seamless JavaScript interop, automatic TypeScript type generation, and first-class React bindings.

Use cases

• write fully typed JavaScript without any types
• compile a typed language to clean JavaScript
• add static typing to an existing JS codebase
• build React apps with a sound type system
• generate TypeScript types from a typed language
• use a fast compiler with instant feedback loops

When to choose

• you want strong static types compiling to idiomatic JavaScript
• you need fast builds and refactoring at any codebase size
• you want React development with built-in JSX and no Babel plugins
• you need seamless two-way interop with JavaScript and TypeScript

When to avoid

• your team is not willing to learn a new language syntax
• you rely heavily on JS ecosystem tooling like Babel or webpack plugins
• you need dynamic typing or rapid prototyping without type annotations
• your project depends on libraries without ReScript bindings and you want to avoid writing them
