What are some examples of function constructors in JavaScript?

Function constructors in JavaScript are special functions used to create objects. For example, you can create a 'Person' constructor like this:

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

You can then create a new person object using new Person('Alice', 30);.

Can you give me another example?

Sure! Here's an example of a 'Car' constructor:

function Car(make, model) {
    this.make = make;
    this.model = model;
}

You can create a new car object like this: new Car('Toyota', 'Corolla');.

What about using ES6 classes instead?

Great question! With ES6, you can use classes to create constructors. Here's how you can define the 'Person' class:

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

You can create a new instance with new Person('Bob', 25);.
