I have the following code snippet in my node code.
var fs = require('fs');
fs.readdir(__dirname, function (err, files) {
console.log(files);
});
Why does the variable '__dirname' have double underscores? I know that one underscore is a naming convention for a private/protected variable... but does double underscore mean something more?
__dirname and __filename are local to each module but with the particularity that are strings.
http://nodejs.org/docs/latest/api/globals.html
documentation specifies:
__dirname isn't actually a global but rather local to each module.
and normally underscore means private ( In Javascript, what does this underscore mean? )
It can be interpreted as a local private variable to the module.
