`babel-walk` provides a tiny, fast AST‑traversal utility for Babel’s AST nodes, offering simple walkers (`walk.simple`, `walk.ancestor`, `walk.recursive`) that are much lighter than `babel‑traverse`. It’s ideal for developers who need straightforward, high‑performance walks of Babel abstract syntax trees—such as static analysis, linting, or code transformation scripts—without the heavyweight overhead of a full‑featured traversal library.
