babel-traverse (legacy, Babel 6 era)

babel-traverse (v6.26.0) is the deprecated Babel 6 package for traversing and manipulating ASTs. It was the core traversal engine behind Babel 6, maintaining tree state and allowing node replacement, removal, and insertion. Key differentiator: provides a visitor pattern for AST mutation via Path objects. Since Babel 7, this package has been replaced by @babel/traverse. v6.26.0 is the final release of the standalone package; it depends on babel-types and babel-generator. It does not ship TypeScript definitions, and is CommonJS-only. The v8.0.0-rc.3 release exists but the babel-traverse name is no longer published under the @babel scope.
