How can I console.log this function using the call() method instead of creating a constant and using the new operator?

```auto
function Circle(radius) {
  this.radius = radius;
  this.draw = function() {
    console.log('hi');
  }
}

const another = new Circle(1);

```

are you trying to call `draw` function without creating `instance` of `Circle`

The lesson was saying that if we use `Circle.call({}, 1)` is the same as using const `another = new Circle(1);`

but if the first implementation is used, I can log the circle object to the console.

`call` method is change the behavior of **`this`** as i remembered `Mosh` said `new Circle(1)` uses `call method` behind the hood
