babel-walk

Lightweight AST traversal library for Babel ASTs, v3.0.1 (released 2023). Provides simple, ancestor, and recursive walk functions that are significantly faster than babel-traverse (~8-16x). Key differentiators: curried API (since v3) for improved TypeScript inference and caching of visitors; no union syntax support; designed for non-transformational walks where performance matters. Release cadence is irregular, with major breaking changes in v2 (rename from babylon-walk, dropped Node <10) and v3 (curried functions).
