How to randomly select a name in an array list

Question

I encountered a problem about an array list. I wanted to return a random name in the array list, but I encountered a problem when implementing it.

``function randomName(names) {
names = ["john", "Ben", "Jenny", "Michael", "Chloe"];
Math.random(names.length);
console.log(names);

    return names + "is going to buy lunch today!";

}

randomName();

I want the output to be:

Michael (or any name in the array) is going to buy lunch today!

Can you guide me on how to achieve this?

Answer 1

const index = Math.floor(Math.random() * names.length);

names[index]
