Javascript number guessing game displaying issues

Question

I have a Javascript assignment where we need to use loops to create a counting betting game. The User enters a number and the computer randomly selects a number between 1-10, and the user can bet up to 10 points to win. We need to display the number the computer guessed, the number of turns(up to 100), and the user's points. I'm having issues with getting the items to display on the webpage and at this time I am showing no errors.

var randomNumber = Math.floor(Math.random() * 10) + 1;
var userNumber = document.getElementById("userNumb");
var points = 10;
var turns = 1;
var bet = document.getElementbyID("userBet");

if (userNumber <= 0 || userNumber >= 11) { // checks to see if user entered a number between 1 and 10
  alert("Please enter a number between 1 and 10!");
  return false;
}

if (bet <= 0 || bet > 10) { // Checks to see if user entered a bet between 1 and 10
  alert("Please enter a bet!");
  return false;
}

function numberGuess() {
  if (userNumber === randomNumber) { //Compares User's number to computer generated number
    points = points + (bet * 10);
    turns++;
  } else {
    points = points - bet;
    turns++;
  }


  if (turns == 100 || points = < 0) { //Game over statement
    alert("GAME OVER! Final points count: " + points);
  }
}

Answer 1

This is an edited version of Tnc Andrei's code. After applying the code it properly displayed in the console. Changed the console.log to

document.getElementById("randomNumber").innerHTML = randomNumber;

in order to have the items displayed properly. I also had to move a few variables into the function to change the random number every click.

Javascript

var points = 10;

function checkNumbers(userNumber, bet) {
  var check = {};

  if (userNumber <= 0 || userNumber >= 11) { // checks to see if user entered a number between 1 and 10

Try This

var randomNumber = Math.floor(Math.random() * 10) + 1;
var points = 10;
var turns = 1;

function checkNumbers(userNumber, bet) {
  var check = {};
  
  if (userNumber <= 0 || userNumber >= 11) { // checks to see if user entered a number between 1 and 10
    return { error: true, message: "Please enter a number between 1 and 10!"};
  }

  if (bet <= 0 || bet > 10) { // Checks to see if user entered a bet between 1 and 10
    return { error: true, message: "Please enter a bet!" };
  }
  return { error: false, message: 'OK'};
}


function numberGuess() {
  var bet = document.getElementById("userBet").value;
  var userNumber = document.getElementById("userNumb").value;
  var check =  checkNumbers(userNumber, bet);
  
  if(check.error) {
    console.log(check.message)
    return;
  }
  
  if (userNumber === randomNumber) { //Compares User's number to computer generated number
    points = points + (bet * 10);
    turns++;
  } else {
    points = points - bet;
    turns++;
  }
  console.log(points, turns);

  if (turns === 100 || points <= 0) { //Game over statement
    console.log("GAME OVER! Final points count: " + points);
  }
}
