What is the method to clearly pinpoint entities from the global namespace in Typescript?

Instead of relying on Javascript's prototype, I am considering utilizing the inheritance feature of Typescript.

My goal is to incorporate some helpful methods in the class String within my designated namespace Util. This way, the String class can implement the global interface String.
How can I distinguish between these two entities? For instance, in C++, we typically use:

namespace Util
{
  class String : public ::String { ...

Is there a Typescript equivalent for :: that signals to the compiler the interface's affiliation with the global scope?

Add-on Question: Is class inheritance the best substitute for Javascript's prototype?
What serves as a comparable alternative to Javascript's "prototype" in Typescript?

Answer №1

Is there a Typescript equivalent for the :: operator to indicate that an interface belongs to the global namespace?

Unfortunately, there is no specific keyword for this in Typescript and the request was denied: https://github.com/Microsoft/TypeScript/issues/983

To prevent naming conflicts, you can create a reference in the global scope:

type GlobalString = String; 
namespace Util {
  // Use GlobalString
}
