Unknown typescript

unknown is the type-safe counterpart of any. 
Anything is assignable to unknown, but unknown isn’t assignable 
to anything but itself and any without a type assertion or a
control flow based narrowing. 
Likewise, no operations are permitted on an unknown without 
first asserting or narrowing to a more specific type
