Why Does My Code Work Even After Major Changes?

I think this might be related to how your code handles default exports and named exports. Since you mentioned using 'export default', remember that it doesn't matter what you name it when importing. A friend of mine pointed this out too; you could have named it one thing but still end up importing the original default function without realizing it.

I’ve seen this happen before, and it's often due to your development environment not updating properly. Make sure you're checking the right imports; sometimes, your IDE might show you a stale version of the file. Restarting your dev server and clearing the cache could also help diagnose the issue.

It sounds like a classic case of a bug where expectations don't match reality. First, double-check where your code is running. Start using a debugger to set breakpoints and step through your code line by line. This will help you see where things are going wrong. If you suspect caching is an issue, try making an input change to see if it reflects in the output. If it doesn’t, you’ve identified a problem! Then, using a divide-and-conquer approach by setting breakpoints in the processing flow may help pinpoint where things start behaving correctly again.
