JavaScript - Check if object is empty

function isEmptyObject ( obj ) {
    var name;
    for ( name in obj ) {
        return false;
    }
    return true;
}

JavaScript set object key by variable

ES6

var key = "name";
var person = {[key]:"John"};
console.log(person); // should print  Object { name="John"}

Before ES6

var person = {};
var key = "name";

person[key] /* this is same as person.name */ = "John";

console.log(person); // should print  Object { name="John"}
