# TODO At the time of this file's creation, the existing examples did not work. The [README](../README.md) has been updated to be generic for any example in its guide. We should create new examples for testing `lang-js` locally without the entire stack. For now, use `dal` integration tests for `lang-js` testing or add new examples to this directory and delete this `TODO.md` file. See [PR #4259](https://github.com/systeminit/si/pull/4259) for more information.
