You can do it like this. Here is no need for a loop:

var person = { 
name : 'Sarah', 
country : 'US', 
age : 35, 
treehouseStudent : true, 
skills : ['JavaScript', 'HTML', 'CSS']

var skills = person.skills;

console.log(skills.join(', '));


you could also just console the raw value of the skills, without space between each array value like this:
