ReScript

What is ReScript?

While TypeScript and Flow—together with many others—are popular languages targeting JavaScript, ReScript has a powerful and elegant type system. Development leverages the mature OCaml (an industrial-strength, general-purpose programming language supporting functional, imperative, and object-oriented features) community and its aggregated knowledge base. Seamlessly merging many type-driven development concepts, ReScript’s JavaScript compiler is incredibly fast, eliminates dead-code, and supports native and JavaScript as compiler targets, enabling code to be written once and run anywhere.

Why we like ReScript

Created to solve real-world problems in production-grade applications, ReScript addresses the shortcomings of using Flow and TypeScript for a type-safe language for our frontend React JS code. Our development services build apps offering a higher degree of security and fewer bugs. We’ve been using ReScript since mid-2018.

It’s got big backers!
