JavaScript获取下一个星期二或星期五的日期（最近）

Question

I need to code a function that returns the date (example: 2014/08/28) of next tuesday or next friday, whichever is the closest day. But there is a little quibble: if today's day is tuesday or friday, if it is before 22:00 it should return todays date, on the other hand if it's after 22:00 or equal to 22:00 it should return next tuesday's or friday's date, whichever it's the next one.

I've no clue on how to start coding this.

Regards,

Check the sninppet below. Maybe I could make it more optimised but more or less, I just followed the pseudo-code from the comments above.

function closest_tuesday_or_friday() {
  var today = new Date(), tuesday, friday, day, closest;

  if(today.getDay() == 2 || today.getDay() == 5){
    if(today.getHours() < 22){
      return today.getFullYear() + "/" + (today.getMonth() + 1) + "/" + today.getDate();
    }
  }else{
    day = today.getDay();
    tuesday = today.getDate() - day + (day === 0 ? -6 : 2);
    friday = today.getDate() - day + (day === 0 ? -6 : 5);
  }

  if(tuesday < friday){
    closest = new Date(today.setDate(tuesday));
  }else{
    closest = new Date(today.setDate(friday)); 
  }
  return closest.getFullYear() + "/" + (closest.getMonth() + 1) + "/" + closest.getDate();
}

console.log(closest_tuesday_or_friday());
