What is the difference between Modules and Namespaces in TypeScript/JavaScript?

Question

I tried to compile the following code in TypeScript to JavaScript:

namespace MyNamespace {
    class MyClass {
        public test() {
            return 1;
        }
    }
}

If I replace the keyword namespace with module, it still generates exactly the same JavaScript code. So what is the difference between a module and namespace and when should I choose one over another?

They are both exactly the same. module causes confusion with Native JavaScript (e.g ES6 module) so they decided to rename it to namespace.

In new code prefer to use namespace.
