[SOLVED]Why infinite loop is happening?

1 
function smallestCommons(arr) {
  var y = Math.max(arr[0],arr[1]);
  var x = Math.min(arr[0],arr[1]);
  var array = [];
  var multiple = [];
  for(var i=x;i<(y+1);i++){
    array.push(i);
  }
  var max=1;
  for(var l=0;l<array.length;l++) max = max*array[l];
  for(var z=y;z<(max+1);z++){
    var check=0;
    for(var w=0;w<array.length;w++){
      var result = z%array[w];
      if(result===0) check++;
      else break;
    }
    if(check===array.length) multiple.push(z);
     
  }
  var final = Math.min.apply(Math,multiple);
  return final;
}// end of function


smallestCommons([23, 18]);

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.

Is it an infinite loop or just so slow that the FCC loop protection thinks it might be an infinite loop?

Yes you are right.My code is working in chrome’s console
