**prr** is a lightweight utility that simplifies the use of `Object.defineProperty()` by providing a more intuitive API for setting object properties with configurable options like `enumerable`, `configurable`, and `writable`. It’s designed for developers who want a cleaner, more concise way to define object properties, especially in environments where ES5 support is available, and it gracefully falls back to standard property assignment in older environments. The project is particularly useful for Node.js and frontend developers using npm or Ender.
