Want to check function body of console.log in NodeJS

Question

I want to see function body of console.log function. To check this I tried following code :

console.log(console.log.toString())

It prints only

function () { [native code] }

So how can I check this code?

You can't. It is a native function, which under most browsers means it is written in a lower-level language like C.

If you can explain why you would like the source, we might be able to help.

When I pass circular object to console.log,it prints correctly. Whereas when I use winston for logging & pass circular object,it goes into infinite loop.So I want to check ,how it is handled in console.log. – Abhishek Kulkarni Mar 09 '16 at 05:14

Each browser is free to handle it howeer they'd like.. but -- there are some JSON encoders that can handle circular data. One of them might be able to help you. http://stackoverflow.com/questions/9382167/serializing-object-that-contains-cyclic-object-value or google for Circle JavaScript Encoder. – Jeremy J Starcher Mar 09 '16 at 05:42
