Retrieve the current javascript file name and line number

Is there a standard way of accessing the current file name of a script?

Is there something like __FILE__ and __LINE__ in C++ or PHP.

If there is no standard way of doing this, what are the tools that would allow to add such functionality to .js files (preprocessing)?

I am not looking for browser specific solutions (i.e. ReferenceError: document is not defined)

If you're using NodeJS you can use __filename or module.filename, however in the browser, no you can't.

I'm not sure what you're using, but in node.js you can do it like this

file.js

var path = require("path");
console.log(path.basename(__filename));
// => file.js

There's no way to do this in the browser though.
