    if(random_keeper === 0){

    }
    if(random_keeper === 1){
        question_peeker =  question_2;
    }
    if(random_keeper === 2){
        question_peeker =  question_3;
    }
    if(random_keeper === 3){
        question_peeker =  question_4;

const questions = [question_1, question_2, question_3, question_4];
function random_number(){
    random_keeper = Math.floor(Math.random() * 4);

    question_peeker = question[random_keeper];
}

const questions = [question_1, question_2, question_3, question_4];
function random_number(){
    random_keeper = Math.floor(Math.random() * 4);

    question_peeker = question[random_keeper];
}

so u mean i just put all the question in 1 other array ?

yeah though I'd also not use an array for the questions, much better to use an object:

const question_1 = {
  id: 1,
  question: "What does HTML mean?",
  answer_index: 0,
  answers: ["html","css","grid","flex"]
}

const question_1 = {
  id: 1,
  question: "What does HTML mean?",
  answer_index: 0,
  answers: ["html","css","grid","flex"]
}

it also looks like your function is modifying the global scope directly, which isn't a good idea. You've got something like let question_peeker; somewhere, and you're setting its value in the function? It's generally a good idea to have functions only ever modify their own scope, and return things if you need data out of them:

function random_number(){
    random_keeper = Math.floor(Math.random() * 4);

    return question[random_keeper];
}

let question_peeker = random_number();

function random_number(){
    random_keeper = Math.floor(Math.random() * 4);

    return question[random_keeper];
}

let question_peeker = random_number();

also, that function does not return a random number, so you should probably rename it to something more appropriate. Naming is hard, but also super important
