constructor Property

Every object’s prototype has a constructor property that references the function used to create that object. It is useful for checking the origin of an instance or creating new instances of the same type.

Code Example

function User(name) {
  this.name = name;
}
const user = new User("Alice");
console.log(user.constructor === User); // true
console.log(user.constructor.name); // "User"

// Create another user using constructor
const another = new user.constructor("Bob");
console.log(another.name); // "Bob"
