What is the TypeScript equivalent of the Java interface.class?

Can you write a Java code in TypeScript that achieves the same functionality as the code below:

Class<?> meta = Object.class;
and

meta = Processor.class; // Processor is an interface

In TypeScript, what would be the equivalent of .class? Specifically, in the case of an interface. If Processor were a class, I could simply remove .class and it has worked for me so far.

Updated Example:

public interface ObjectProcessor {}
public interface StreamCloser {}

public interface Registry {
  void register(Object value, Object metadata);
}

public class RegistryImpl implements Registry {
  void register(Object value, Object metadata) {}
}


RegistryImpl registry = new RegistryImpl();


Object value = ?; //any value
Class<?> meta = Object.class;

if (value instanceof ObjectProcessor) {
  meta = ObjectProcessor.class;
} else if (value instanceof StreamCloser) {
  meta = StreamCloser.class;
}

registry.register(value, meta);

Answer №1

In the realm of programming, classes hold a unique status. In contrast to Java where classes are treated as functions and given first-class treatment, they can be passed around freely.

  const meta = Object;

The concept of .class in statically typed languages like Java serves as a portal for reflection, offering insights into class details such as properties and methods. However, JavaScript operates differently in this regard.
