Acorn JSX Parser Plugin

acorn-jsx is a plugin for the Acorn JavaScript parser that provides capabilities to parse React.js JSX syntax. It transforms JSX source code into an Abstract Syntax Tree (AST), which is then consumed by various language tools and transpilers like Babel and Buble. The current stable version is 5.3.2. This package maintains a moderate release cadence, often aligning with updates to the Acorn parser itself or changes in the JSX specification. Its key differentiators include its small footprint, speed, and JavaScript-only implementation, making it a widely adopted core component for JSX parsing in the JavaScript ecosystem. It strictly focuses on parsing to AST, rather than performing any transpilation to ES5-compliant JavaScript.
