JS Practice — Built-in Objects

Reflect.deleteProperty — typeof

📖 Usage Example

const obj = { a: 1, b: 2 }
Reflect.deleteProperty(obj, 'a')
console.log(obj)              // → { b: 2 }
console.log('a' in obj)       // → false

Reflect.deleteProperty() deletes a property from an object, returning true on success, just like the delete operator.

typeof Reflect.deleteProperty

Reflect.deleteProperty is a static method, so typeof Reflect.deleteProperty returns 'function'.

Challenge: Verify that typeof Reflect.deleteProperty returns 'function'.
