node JavaScript files and global namespace

Question

When writing JavaScript for webpages it is good practice to wrap files in an anonymous self-executing function to avoid polluting the global namespace. See What is the purpose of wrapping whole Javascript files in anonymous functions like “(function(){ … })()”?

When writing JavaScript files in a server-side NodeJS environment is it still useful to wrap my files in this anonymous function?

One of the benefits of node modules is that nothing is global by default as a module is already in it's own private namespace. So only things you explicitly attach to the `global` object will be global. — jfriend00, Sep 10 '15 at 05:57

No you don't need to do that in Node, your code is already wrapped in a function by default:

(function (exports, require, module, __filename, __dirname) {
  // YOUR CODE INJECTED HERE!
});
