by REPLY2SAGAR

JavaScript

function Person(firstName, lastName, age) {
    this.firstName = firstName;
    this.lastName = lastName;
    this.age = age;

    this.isAdult = function() {
        return this.age >= 18;
    };
}

// Creating an instance of Person
const alice = new Person("Sagar", "Salunke", 25);
console.log(alice.isAdult());  // Outputs: true
console.log(alice.firstName);  // Outputs: Alice
