I've changed how we check the attribute prefix. It turns out that using String.prototype.slice is much faster than the other approaches we tested a while ago.
The previous method that checked fixed positions is ~72% slower than the current one using slice. 😄

We have e2e tests for full vDOM hydration, islands, and some directives. If none of them has broken, I guess these changes work. 🤞 |

What
Move all
wp-prefixes (or strings containing any of them) to a constants file.Why
To make it easier to change them if necessary (e.g.,
directivePrefixtodata-wp-).How
Creating a
constants.jsfile.https://github.com/WordPress/block-hydration-experiments/blob/4990097fef3f3c674eee195a3ea4bb2fd460c7cd/src/runtime/constants.js#L1-L3
I defined separated prefixes for components and directives, just in case we finally go for HTML-compliant directives (i.e., using custom data attributes).
