How to check if my object is empty in javascript

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.

An object can have non-enumerable properties. – T.J. Crowder Jun 12 '18 at 08:11
I am getting following error :TypeError: Object.keys called on non-object – Meenakshi Rathod Jun 12 '18 at 08:35
@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](https://stackoverflow.com/questions/50812197/how-to-check-if-my-object-is-empty-in-javascript#comment88629635_50812197)? – T.J.
