Challenge 1.4: Checking Properties - my shorter solution

[Wavez]

I think the following solution should be added:

1. It is shorter
2. use of prototype is not something necessary for that specific question spirit, maybe question should be improved

var key,
obj = {
name: 'john',
surname: 'doe'
};

for (key in obj) {
if (obj.hasOwnProperty(key)) {
if (key != "name") {
console.log(key + ' exists in obj');
console.log(key + ': ' + obj[key]);
continue;
}
else console.log(key + " doesn't exist in obj");
}
}
