EDIT BELOW

I created an array consisting of foods, for example 'apple', 'banana', 'orange', 'cherry' etc. Now I need something to randomly select 3 elements from this array, without selecting the same thing twice (for example not 'orange' 'orange' 'banana'). I have searched for a solution myself, but I'm fairly new to coding and don't really understand everything. Can someone help me a little bit?

EDIT: I think I found a way using

const randomSelectionH = (n) => {
  let newArr = [];
  if (n >= healthy_foods.length) {
    return healthy_foods;
  }
  for (let i = 0; i < n; i++) {
    let newElem = healthy_foods[Math.floor(Math.random() * healthy_foods.length)];
    while (newArr.includes(newElem)) {
      newElem = healthy_foods[Math.floor(Math.random() * healthy_foods.length)];
    }
    newArr.push(newElem);
  }
  return newArr;
}

But now, I need to use this to put the random selection into a html-button-response

I used:

var trial_two_choices = {
  type: 'html-button-response',
  stimulus: '<p>What food</p>',
  choices: [randomSelectionH]
}

But this returned an error. trying to make a variable out of the randomSelectionH and putting that as choices didn't resolve the issue. Any idea on what to do?
