There was a problem hiding this comment.
maybe instead of this - which could allow much more complex patterns - we just bail out if [...name].length === 1?

That would certainly work for me. Do we still want to disallow a single lowercase letter as the name?

since anything that starts lowercase isn't a custom component, it's an html component, i don't think this rule would warn on it?

Ah cool, in which case I'll make that change. Thanks.

Fixes #2394.
$ and _ are valid names for components that are neither upper nor lower
case. This change ensures the pascal case rule only applies to the rest
of the component name (if any).
