Google Proposes JSIR as a High-Level IR for JavaScript

14 hours ago

Google engineers are developing JSIR, a high-level intermediate representation for JavaScript, currently used in production for code analysis, transformation, and deobfuscation.
JSIR aims to address the gap in JavaScript tooling by providing an IR alternative to traditional AST-based approaches, building on LLVM and MLIR communities' work.
The project is open-source and available on GitHub, with Google soliciting interest from LLVM/MLIR developers to upstream JSIR into MLIR.
