JSX is a statically-typed, class-based programming language developed at DeNA that compiles to JavaScript, aiming to be faster, safer, and easier than plain JavaScript. It ships as an npm-distributed compiler toolkit with a jsx(1) CLI for compiling, running, optimizing, and testing JSX source files.
Use cases
- compile a statically-typed language to javascript
- write class-based oop code that runs in browsers
- optimize javascript performance via compile-time optimizations
- run and test altjs source files from the command line
- port performance-critical javascript libraries to a typed language
When to choose
- you want static typing and a Java-like class system targeting javascript
- you need compile-time type checking and optimizations for browser or node code
When to avoid
- you need an actively maintained toolchain - the last release was 2021 and the project is dormant
- you prefer modern alternatives like TypeScript
- you need a large ecosystem or community support
