How to display total points?

Just finished the "Build a simple site with Node.js" course. I decided to play around a little with the code to learn it better.

What I'm trying to do is show the total number of points. I can't seem to figure out how to do it though.. if I try to call anything after profileJSON.points like the javascriptPoints set up, profileJSON.points.JavaScript, I get errors.

I'm assuming I need a loop to get through the points, but I'm not sure how to set that up. Any help would be awesome

studentProfile.on("end", function(profileJSON){
    //show profile


    //Store the values which we need
    var values = {
      avatarUrl: profileJSON.gravatar_url, 
      username: profileJSON.profile_name,
      badges: profileJSON.badges.length,
      javascriptPoints: profileJSON.points.JavaScript,
      totalPoints: ???
    }

In this case, you just need to grab the profileJSON.points.total property to get the total number of points for that user. Is that what you were after?

Otherwise, you would need to loop over the properties in the profileJSON.points object and sum the values, not including the one for the total property.

Something like this:

var totalPoints = 0;
for (var topic in profileJSON.points) {
  if (topic !== 'total') {
    totalPoints += profileJSON.points[topic];
  }
}
// totalPoints should now hold the same value as profileJSON.points.total

Ahh, thank you! Was having a major brain fart on that one.
