nodejs function to string containing function's code

Question

I am really really new to nodejs. Is there any way to convert function content to string? Something like, if I have:

function() {
    ....
}

I'd like to have "function() { .... }".

Is such thing possible?

Did you try (function() {...}).toString()?

Functions already have a toString() method... so just (function() {}).toString() should work.

For example, in the node REPL:

> (function() { console.log("hello"); }).toString()
'function () { console.log("hello"); }'

Here's a link to some documentation.

@kamituel I believe Function.prototype.toString() is standard. The indentation parameter referenced in the MDN docs is non-standard, but this solution doesn't rely on that.
