Answer 1

I also had the infinite loading issue with the following function.

// check if an item can be checked off
function checkedOff( need, have ) {
  var retStr = "nope";
  if( have >= need ){
    retStr = "yep";
  }
  return retStr;
};

Turns out you shouldn't have a trailing ";". Removing the semicolon solved the problem.

// check if an item can be checked off
function checkedOff( need, have ) {
  var retStr = "nope";
  if( have >= need ){
    retStr = "yep";
  }
  return retStr;
}

This runs as one would expect.
