This is similar to what I have been trying to do,
var obj = {};
if(obj){
//do something
}
What i want to do is that the condition should fail when the object is empty.
I tried using JSON.stringify(obj) but it still has curly braces('{}') within it.
You could use Object.keys and check the length of the array of the own keys.
function go(o) {
if (Object.keys(o).length) {
console.log(o.foo);
}
}
var obj = {};
go(obj);
obj.foo = 'bar';
go(obj);
You can check if the object is empty, i.e. it has no properties, using
Object.keys(obj).length === 0
Object.keys() returns all properties of the object in an array.
If the array is empty (.length === 0) it means the object is empty.
You can use Object.keys(myObj).length to find out the length of object to find if the object is empty.
working example
var myObj = {};
if(Object.keys(myObj).length>0){
// will not be called
console.log("hello");
}
myObj.test = 'test';
if(Object.keys(myObj).length>0){
console.log("will be called");
} 
Object.keys(obj).length.
