Object-Scan is a JavaScript library designed for traversing object hierarchies using matching patterns and callbacks. It is particularly useful for developers who need to efficiently search and manipulate complex nested data structures. The library supports a wide range of matching syntax, including wildcards, regex, and arbitrary depth recursion, making it highly versatile for various use cases. With its dependency-free design and tiny bundle size, Object-Scan is optimized for performance and ease of integration. It is ideal for developers working with JSON-like data structures who require precise and flexible traversal capabilities.
