ObjectObject.getOwnPropertyDescriptorsintermediate

Object.getOwnPropertyDescriptors() — inspect all flags

📖 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() — checking every descriptor

You can use the result to inspect flags for every property at once.

Challenge: Implement allEnumerable(obj) that returns true if every own property is enumerable.

allEnumerable({ a: 1, b: 2 }) // → true
💡 Hints (1)
  • • Use `Object.values(descriptors).every(d => d.enumerable === true)`.
