Right, so I guess I'm not understanding your point about why comparing two languages like this is ridiculous. Java has a full blown runtime reflection system (it's "types exist at runtime"). JS doesn't. So Java wins in the reflection category.
- tracker1 8y agoBut in JS, reflection is pretty much not needed... I don't need to use reflection to see if an object has a quack method, or that I call it with the right types... I just call instance.quack() ... It's up to you as the developer to keep your interfaces and composition in line. It's actually WAY easier than with C# or Java. Since the use-case of reflection itself is largely unnecessary.
- lopatin 8y agoCalling a method and seeing what happens is not a substitute for reflection. You can do that in Java too btw.
