Arrays Error - Undefined

Can anyone spot the error in the following? I'm getting 'undefined'.

var friends = ["Nick", "Mike", "Tom", "Ron"];
console.log(friends.length);  

for(var i=0; i < friends.length; i+=1); {
    console.log(friends[i]);
}

I think it's something to do with i.

Thanks,

for(var i=0; i < friends.length; i+=1); { console.log(friends[i]); }

Because you have a semi-colon at the end of "i+=1);"

It should be:

for(var i=0; i < friends.length; i+=1) { console.log(friends[i]); }
