How to get array in property?

For example: How to console all skills in person with 'for in' loop?

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

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:

console.log(person.skills);
