object property values are showing up as undefined in a loop, any ideas as to why? 

var students=[
{name: 'john',
 age:20,
 track: 'ios',
 achievements: 40,
 points: 200},
{name: 'tom',
 age:21,
 track: 'java',
 achievements: 60,
 points: 660},
{name: 'dave',
 age:30,
 track: 'nod.js',

 achievements: 30,
 points: 303},
{name: '50',
 age:90,
 track: 'ruby',

];

for(var i=0; i< students.length; i+=1){

    for(var prop in students[i]){ 
       console.log( prop + ": " + students[prop])
  }
}

Hey there Brandon,

the problem is that you have an array but when you're trying to log the properties of the object to the console you're not specifying at which position of the array the object is. So you're basically trying to get the property of an array.

console.log( prop + ": " + students[prop])

If you add the index i before the property it should work fine. Like so:

console.log( prop + ": " + students[i][prop])

I hope that helps! :)
