javascript - nodejs function to string containing function's code - Stack Overflow

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()? – Benoir Commented Apr 3, 2013 at 17:10

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.
