JavaScript Accessor Descriptor Checker

The `is-accessor-descriptor` package provides a focused utility function to determine if a given JavaScript value, or a property on an object, represents a valid accessor property descriptor. It specifically checks for the presence of `get` and/or `set` properties and ensures they are functions, while rejecting `value` or `writable` properties which characterize data descriptors. Currently at version 3.0.5, this package is part of a family of descriptor-checking utilities under the `inspect-js` scope, emphasizing foundational JavaScript introspection. Its release cadence is stable and infrequent, reflecting its role as a fundamental helper. It differentiates itself by its precise focus, allowing developers to isolate and validate accessor descriptors without conflating them with other descriptor types, making it a reliable tool for metaprogramming and object property manipulation.
