Plain javascript gut check if object is empty or not

isObjEmpty.js

var yourObjectHere = {};
Object.getOwnPropertyNames(yourObjectHere).length === 0; // empty object true

var yourObjectHere = {'empty':'i am not empty!!'};
Object.getOwnPropertyNames(yourObjectHere).length === 0; // empty object false

// function isEmpty(obj) with object param

var isEmpty = function(yourObjectHere) {
for (var key in yourObjectHere) return false; return true;
}

// empty object will return false and vice versa
