How to clear billing form validation errors when using Magento UI components
A “quick” (har har) answer from me on how to reset a form field’s validation state in the Magento 2 checkout application. This is also a nice example of how, no matter how far we progress with computers doing things for us, it’s always going to be useful to reason about how a computer does the things it does.

If you want to be successful with any customizable/programmatic information system – hire developers who know what they’re doing, know how to figure things out when they don’t, treat them like human beings, expect they do the same for you, and make your success their success. Chose systems your developers can reason about, and avoid systems they can’t.
