JS Practice — Built-in Objects

Reflect.has — typeof

📖 Usage Example

const obj = { a: 1 }
console.log(Reflect.has(obj, 'a'))  // → true
console.log(Reflect.has(obj, 'b'))  // → false
// Equivalent to: 'a' in obj

Reflect.has() checks whether an object has a property, equivalent to the in operator.

typeof Reflect.has

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

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