Object.getOwnPropertyDescriptor is a JavaScript method that returns a property descriptor for a named property of a given object, if it exists directly on the object. This descriptor provides metadata such as the value, writability, enumerability, and configurability of the property, enabling detailed control and inspection of object properties.

Object.getOwnPropertyDescriptor

JavaScript method

A property descriptor in JavaScript is an object that describes the attributes of a specific property within an object, allowing for precise control over its behavior, such as configurability, enumerability, and writability. By using methods like Object.defineProperty, developers can manipulate these attributes to create properties with specific characteristics, thereby enhancing the flexibility and security of object properties.

Value is a multifaceted concept that represents the worth or importance of something, whether in economic, ethical, or personal terms. It plays a crucial role in decision-making, influencing choices by determining what is considered beneficial or desirable.

Value

Writability refers to the ease with which a language structure can be written accurately and efficiently by its users. It encompasses aspects such as syntax clarity, cognitive load, and the intuitiveness of code elements in programming languages, impacting both novice and experienced developers' productivity.

Writability

Enumerability refers to the property of a set that allows its elements to be listed in a sequence, typically implying that the set is countable, such as the set of natural numbers. This concept is fundamental in mathematics and computer science as it helps distinguish between countable and uncountable sets, impacting the understanding of algorithms and computational limits.

Enumerability

Configurability refers to the adaptability of a system or product to be customized by the user to meet specific needs or preferences without requiring extensive redesign or engineering. This enhances user experience and extends the utility and lifespan of the product by allowing for personalization and flexibility in operation.
