What is the purpose of `Object.defineProperty()` and when must you use it instead of direct assignment?

Accepted Answer

`Object.defineProperty()` is used to set property descriptor attributes and define getters/setters. This is necessary when you need non-enumerable properties, non-writable constants, or non-configurable properties. It's also used for getter/setter accessor properties.
