Using for..in loop and wrapping properties with different html tags

I just wondering is it possible to get similar result to Dave's solution (when the name of the student is wrapped with <h2> tag and the rest is wrapped in <p>) while using for..in loop like this:

function getStudent( student ) {
  for (key in student) {
    outputHTML += '<p>' + key + ': ' + student[key] + '</p>';
  }
  return outputHTML;
}

In other words, how to access very first key in the loop and apply to it <h2> tag and for the other keys just <p>.

Hopefully my question is clear. Thanks

Hey Max,

Yes, it is possible. here is one way to do it.

function getStudent(student) {
    var outputHTML = "";
    for (var key in student) {
        if(key === "name"){
            outputHTML += '<h1>' + key + ': ' + student[key] + '</h1>';
        } else {
            outputHTML += '<p>' + key + ': ' + student[key] + '</p>';
        }
    }
    return outputHTML;
}

document.write(getStudent({
    name: 'Jordan',
    track: 'PHP Development',
    achievements: '55',
    points: '2025'
}));

Here is a jsFiddle Demo

Not a problem. sometimes you just need a fresh pair of eyes. I often have the same problem but giving it a break and coming back to it helps you see what you couldn't before.

Glad I could help.
