The type the author presents is not the “User Profile” but a “User Profile Load Resource” (or something in those terms).

When you actually design interfaces you discover that there are way more states to keep in mind when implementing asynchronous loading.

1. There’s an initial state, where fetching has not happened yet

2. There may be initial cached (stale or not) data

3. Once loaded the data could be revalidated / refreshed

So the assumption that you either are loading XOR have data XOR have an error does not hold. You could have data, an error from the last revalidation, and be loading (revalidating).

When you have tree data structures you cannot use regexps or a simple parsers, since the full text may be split in different nodes.

With attributes strings it’s trivial, you just need to move attributes accordingly and to normalize stuff at the end.

It’s such an elegant structure and I don’t understand why is so unknown.

Incredible article btw
