n JavaScript, a constructor is a special method used for creating and initializing objects of a class. It is typically defined within a class and is invoked automatically when you create a new instance of the class using the new keyword.

The constructor method is responsible for setting up the initial state of an object by assigning values to its properties or performing any necessary setup operations. It is often used to accept arguments that are used to customize the object's initialization.

Here is an example of a constructor in JavaScript:


class Person {
  constructor(name, age) {
    this.name = name;
    this.age = age;
  }
}

// Creating a new instance of the Person class
const john = new Person("John Doe", 30);

console.log(john.name); // Output: John Doe
console.log(john.age); // Output: 30
