1. **Package Support**: Node.js supports npm package searching and installing on the fly. You can search for any package and add it to your project, generating a `package.json` file for you, where you can then import it into your program. More on that in our [packager](/site/blog/packager) announcement.
4. **Infinite Loop Protection**: Finally, if you accidentally write an infinite loop (we've all been there), your browser won't be locked up, since the code is not running on your machine.
We made this change because we believe it will be beneficial to Repl.it users, both new and old. We welcome any feedback in the comments below, and we look forward to working with you in the future to create awesome projects.
