Esrecurse provides ECMAScript AST recursive traversing functionality, based on an AST recursive visitor. It’s useful for walking an ESTree-style syntax tree and running custom visitor logic for specific node types, including options to customize child traversal and handle unknown nodes via fallback behavior.

Recent updates
v4.3.0
8/31/2020Release v4.3.0 updates the project version and CI configuration, and bumps the core dependency estraverse. It also adds a new test case for traversing ESTree ChainExpression nodes (related to optional chaining).
Featuresv4.2.1
2/26/2018v4.2.1 makes a small runtime modernization of esrecurse.js by replacing older polyfills (object-assign, Array.isArray fallback, and Object.keys fallback) with native built-ins. It also raises the supported Node.js engine minimum version from >=0.10 to >=4.0 and removes the object-assign dependency.
