How to check if my object is empty in javascript [duplicate]

Question

I have a object as follow:

this.student = {};
this.student.id = '';
this.student.name = '';
this.student.class = '';
this.student.percentage = '';

How do i check if my student object is empty or not?

Stack Overflow is a very active place. When you post a question (or answer), please stick around for a few minutes so you can clarify things, such as Nikhil's question above. Everyone seems to have interpreted your question as being about a truly empty object (no properties), but looking at your question, I suspect that's not correct... — T.J. Crowder

An object can have non-enumerable properties.

I am getting following error :TypeError: Object.keys called on non-object

@MeenakshiRathod - You will not get that error from the code above if it's used after the code in your question. Why not answer the question you were asked half an hour ago?
