so I want to pick a random string from my array and console.log it. My code is returning undefined.

var array = [
    "Hello",
    "Hi"
];

var message = array[Math.random() * array.length];

console.log(message)

In the var message I am trying to get a random message from array. Any help would be great!

You were close, you just have to floor the index since it doesn't work with non-integer values. – John Montgomery Nov 02 '20 at 20:45
console.log(Math.random() * array.length) – epascarello Nov 02 '20 at 20:45
Try `Math.trunc(Math.random() * array.length)` – kol Nov 02 '20 at 20:46
