Consider the deleteProperty trap. If a proxy intercepts a deletion, the developer needs to perform the actual deletion on the target object. The "old school" approach would be to use the delete operator directly: delete target[property] . While this works in simple scenarios, it is fundamentally flawed in a world of inheritance and complex object models. The delete operator is a blunt instrument; it returns a boolean regarding the success of the operation, but it can mask issues related to non-configurable properties. If a property is non-configurable, delete should throw a TypeError in strict mode, but managing these edge cases manually is error-prone. Reflect.deleteProperty() handles this logic automatically, returning a boolean that aligns perfectly with the expectations of the Proxy trap, ensuring the proxy behaves exactly like a native object would.
