def isJSDefaultParam(using Context): Boolean

Is this symbol a default param accessor for a JS method?

Is this symbol a default param accessor for a JS method?

For default param accessors of constructors, we need to test whether the companion class of the owner is a JS type; not whether the owner is a JS type.

def isJSExposed(using Context): Boolean

Tests whether the given member is exposed, i.e., whether it was originally a public or protected member of a non-native JS class.

Tests whether the given member is exposed, i.e., whether it was originally a public or protected member of a non-native JS class.
