How to randomly take a key in js?

Question

JavaScript

I have this code on nodejs:

when I run the script, I need to use these keys several times in the script and so that they are taken randomly, but I run the script, output them for example console.log (k) several times and I ALL 10 TIMES ONE AND SAME KEY Aaaaa WHY??7

Answer 1

function RandomKey() {
return key[Math.floor(Math.random() * (key.length))];
}

console.log(RandomKey());
console.log(RandomKey());
console.log(RandomKey());

Answer 2

Well, it's all logical. the script was loaded - fulfilled - in a variable k there is a value. of course console.log(k) will produce it.
make a function, for example, on a button click, so that the variable k is updated
