has-own-property

This library provides a simple, reliable function to determine if an object has a property defined directly on itself, rather than inherited from its prototype chain. It serves as a safer alternative to the built-in Object.prototype.hasOwnProperty method, which can be overridden or cause errors when called on objects that don't inherit from Object.prototype.

Key Features

• Safe Property Checking — Works reliably even on objects created with Object.create(null) or those that have overridden the hasOwnProperty method.
• Simple API — Exports a single function with a clear signature: hasOwnProperty(object, name).
• TypeScript Support — Includes TypeScript definitions for enhanced type safety and developer experience.
• Lightweight — Minimal dependencies and small bundle size, making it suitable for any JavaScript environment.

Philosophy

The project emphasizes reliability and simplicity, offering a focused utility that addresses a common pitfall in JavaScript property checking without unnecessary complexity.
