Similar packages

Other packages similar to @typescript-eslint/visitor-keys

eslint-visitor-keys

This package provides a list of visitor keys for traversing the AST of JavaScript code. It is similar to @typescript-eslint/visitor-keys but is tailored for JavaScript rather than TypeScript. It is used by ESLint to work with its own rules and plugins.

babel-types

While not a direct equivalent, babel-types is part of the Babel ecosystem and provides definitions for various AST node types, builders, and assertion methods. It can be used to traverse and manipulate ASTs for both JavaScript and TypeScript, offering a broader scope compared to @typescript-eslint/visitor-keys.

estraverse

Estraverse is a simple and flexible library for traversing and replacing nodes in an ECMAScript AST. It is not TypeScript-specific but can be used with JavaScript ASTs. It provides a similar traversal functionality but does not rely on a predefined set of visitor keys.
