the sequence of If statement

http://ift.tt/2r0rs5P

 if(resultArray.includes(result))
  {
    pickRandom();
  }
 if (resultArray.length === max)
  {
    alert("you ran out of number");
  }
 else
  {
    resultArray.push(result);
    document.getElementById("result").value = result;
  }

hi guys... I can't understand the logic behind this

I have 2 IFs statements, but in this case if I put the resultArray.length === max IF statement in second, it will result in undesirable result such as being triggered before all 48 numbers were randomly picked

if I put the resultArray.length === max IF statement first, then it will pick all 48 numbers before alerting...
