ReferenceError: PublicKeyCredential is not defined

Looks like platformAuthenticatorIsAvailable is missing a check for whether PublicKeyCredential is defined at all: https://github.com/MasterKale/SimpleWebAuthn/blob/master/packages/browser/src/helpers/platformAuthenticatorIsAvailable.ts#L8. Maybe just add (await browserSupportsWebAuthn()) && ..?

Also, minor nitpick: isPlatformAuthenticatorAvailable would seem like a more sensible name to me since it’s actually phrased like a question and not a statements plus it’s a little closer to the original method name. Food for thought 😊

My intention with naming the feature check methods what they are right now was to make the if statements they get used in sound almost like normal sentences:

Yeah that came to me as well after writing my comment. I guess it doesn’t really matter as long as the naming is somewhat consistent - and your version is in fact more consistent with browserSupportsWebAuthn. Well, you know what they say about naming in programming 😄 . Anyway, enough with the bikeshedding 🙊

This issue has been fixed in the new @simplewebauthn/browser@4.1.0.
