adding random value to array and comparing first two value js

I am trying to learn some simple things in js, so what i am trying to achieve is every time I get a random number I want to add it inside an array at he front, then compare the first two values make sure they are not [6,6]

function randomNumber() {
  number = Math.floor((Math.random() * 6) + 1);
  return number;
}

function addValue() {
  var score = [];
  score.unshift(randomNumber());
  console.log(score);
  return score;
}

At the moment what is happening, every time i call the randomNumber the array only stores one value, it does not append it to the list and overweights the previous.

What am I doing wrong and why is it working? thx

the variable you use to store the array needs to be created and passed through the argument list, or stored globally. when you do var x = [] you are create a NEW empty array.

  var score = [];
  
  addValue(score);
  addValue(score);
  addValue(score);

function randomNumber() {
  number = Math.floor((Math.random() * 6) + 1);
  return number;
}

function addValue(score) {

  score.unshift(randomNumber());
}

console.log(score)
