Difference between angular 2 modules and Javascript ES6 modules

Question

Angular 2 modules allow apps to be divided into multiple modules, each serving a different purpose.

But isn't that what ES6 modules also supposed to do? What is the difference between the two?

Answer 1

Taken from angular.io:

The Angular module classes differ from JavaScript module class in three key respects:

1. An Angular module bounds declarable classes only. Declarables are the only classes that matter to the Angular.

2. Instead of defining all member classes in one giant file (as in a JavaScript module), we list the module's classes in the @NgModule.declarations list.

3. An Angular module can only export the declarable classes it owns or imports from other modules. It doesn't declare or export any other kind of class.
