Object.getOwnPropertyDescriptors() — get all descriptors

📖 Usage Example

// Inspect all property descriptors at once
const obj = { a: 1, b: 2 }
Object.getOwnPropertyDescriptors(obj)
// → { a: { value: 1, writable: true, ... }, b: { value: 2, ... } }

Use Object.getOwnPropertyDescriptors() to get all property descriptors of an object, useful when doing a complete clone.

Object.getOwnPropertyDescriptors()

Object.getOwnPropertyDescriptors(obj) returns an object mapping every own property to its full descriptor. Unlike Object.getOwnPropertyDescriptor, it covers all properties at once.

Challenge: Implement getAllDescriptors(obj) that returns the full descriptors map.

getAllDescriptors({ a: 1 })
// → { a: { value: 1, writable: true, enumerable: true, configurable: true } }

💡 Hints (2)

• `Object.getOwnPropertyDescriptors` returns a map of `propertyName → descriptor`.
• Each descriptor includes `value, writable, enumerable, configurable` for data properties.
