object.getownpropertydescriptors ponyfill brings the ES2017 Object.getOwnPropertyDescriptors method to older JavaScript environments. This method retrieves all own property descriptors of a given object, enabling detailed introspection and manipulation of object properties. It is useful when you need to precisely control property attributes like enumerability, writability, and configurability, particularly when dealing with object cloning or inheritance patterns in a cross-browser compatible manner for legacy projects or environments.
