JSON access in loop error

Question

I have a json as

var days = {mon: 1, tue:1, fri: 1}

What I'm trying to do it

var dayswithone =[];
['mon','tue','wed','thur','fri'].forEach(function(day){
    if(days.day){
      dayswithone.push(day);

    }
});

All i have to do is push days with 1 into array dayswithone. But this is giving me days.day as undefined.

You should try this

var dayswithone =[];
['mon','tue','wed','thur','fri'].forEach(function(day){
if(days[day]){
  dayswithone.push(day);

}
});
