Great question! When you remove an extension, you should not lose any existing code in your project. The program will fail to work, though, as the code is no longer valid.

Removing an extension involves switching from Blocks to JavaScript or Python, though.

**Save a copy of your project before removing an extension!** Any time you switch out of Blocks mode, you should always save a copy of your project first, just in case there are any problems switching back.
