Crackles when you bite it. Shows the baker did the work.
Summary
This RFC (Request for Comments) introduces JSIR, a new high-level Intermediate Representation (IR) for JavaScript built on MLIR (Multi-Level Intermediate Representation). JSIR is designed to preserve all information from the Abstract Syntax Tree (AST) and support high-fidelity round-trip conversion between source code, AST, and JSIR. The IR uses MLIR regions to represent control flow structures, making it suitable for JavaScript compiler and toolchain development within the LLVM ecosystem.
