For some reason I am confused about how this specific line or two of code is meant to be written.

var btn1 = new Button({
    x: ,
    y: ,
    width: ,
    height: ,
    color: color(),
    label: ,
    onClick: function() {
        rabbits[].(); 
    }
});

I think I understand I need to call the onClick to the Rabbit.prototype.hop ?
But I don't think I understand how/where.
I tried writing "rabbits[hop].();" but then it says hop is not defined.
I feel like I've forgot the entire first JS course all of a sudden.
I looked back on the arrays class and I still didn't understand. Am I stupid?

Edit: I've never been this confused about JS before since I started learning.
I made sure I understood everything perfectly well before moving on every previous class and right now I'm so lost I'm convinced I lost my brain.

This function format seems 100% new to me, and is appearing for the first time in a Challenge.
I tried googling this to no avail.

Hi Gamar,

The "rabbits" variable is an array of rabbits, and the goal is to write a line of code that will make the rightmost rabbit (the one with the greatest index) hop when the button is clicked. To access an element of the rabbits array, you would use "rabbits[i]" where "i" is the index of the rabbit.

"hop" is a function of the Rabbit object, not an integer, so this cannot be used within the square brackets. However, once you've correctly accessed the rabbit using the appropriate index, you can then use the dot notation to call that rabbit's hop function.

I hope this helps! Please let me know if you have any additional questions!

Hello!
The index "i" is inside a for loop somewhere else though, isn't it?
And the "rabbits[i]" is not in the loop that creates the four rabbits, it's what makes the other three rabbits hop without a player...
I'm so confused :/
