🧹 Originally, we were using _resolvedLanguagePackCoreLocation or passing in an empty string. We moved the logic from outside the function into the function since the caller shouldn't have to change the argument functions if the value is undefined. Instead, the function should handle this.

🧹 Originally, this function was not using async/await. I then realized we had the fetch call and the .then chain. I refactored this so it was easy to test. Now it's clear to the caller this function has asynchronous logic.

🧹 Removed this comment because it's related to createBundlePath and explained in a comment near that function with more details.

| }) | ||

✅ This check was added after modifying the createBundlePath function signature.
