map-obj
A utility to transform object keys and values into a new object with deep recursion and symbol support.
What is map-obj?
Map-obj is a JavaScript library that transforms object keys and values into a new object using a custom mapping function. It solves the problem of manually iterating over objects to modify or filter their properties, offering features like deep recursion and symbol key support. It's particularly useful for data normalization, key renaming, and conditional property inclusion.
JavaScript developers who need to programmatically transform object structures, such as when processing API responses, configuring objects, or implementing data pipelines.
Developers choose map-obj for its concise API, robust handling of edge cases (like built-in objects and symbols), and flexibility in deep transformations without external dependencies.
