What is the purpose of the new keyword?

The new keyword in JavaScript is used to create an instance of a user-defined object type or one of the built-in object types that has a constructor function. When you use new, it does four things: it creates a new object, sets the prototype, binds this to the new object, and returns the new object.

function Person(name) {
  this.name = name;
}

const person1 = new Person("Alice");
console.log(person1.name); // Alice
