neotraverse 1.0: I accidentally built lodash for object trees

Read Original

This article announces the release of neotraverse 1.0, a zero-dependency, TypeScript-first rewrite of the classic traverse library for walking and transforming every node in an object tree. The author explains how the library evolved from a class-based API to a functional, tree-shakeable set of standalone functions, making it a 'lodash for object trees' with about 50 helpers including map, reduce, find, filter, get, set, and path-based queries. The release focuses on improved ergonomics, performance, and tree-shaking support, targeting developers working with complex nested data structures in TypeScript or JavaScript.
