What are parameters in constructors?

Can you explain what parameters in constructors are?

Sure! Parameters in constructors are variables that you can pass to a constructor when creating an object. They allow you to initialize the object's properties.

Can you give me an example of a constructor with parameters?

Of course! Here's a simple example in JavaScript:

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

const myCar = new Car('Toyota', 'Corolla');

In this example, make and model are parameters.

What happens if I don't provide parameters when creating an object?

If you don't provide parameters, the constructor will use default values if they are defined, or it may result in undefined for those properties.

Are parameters in constructors mandatory?

No, they are not mandatory. You can define constructors without parameters, and you can also provide default values for them.
