The Javascript tutorial needs expansion

Javascript gained a number of new features in the past years that are being used extensively these days, but which aren't included in the Javascript tutorial on w3schools.

To name a few examples:

- Prototypes
- Arrow functions
- Callbacks
- Promises
- Then
- Async and Await (<-- asynchronicity)
- Iterators and Generators (async iterators and generators)
- Modules (export, import, dynamic imports)

The Javascript tutorial would be improved and made up to date by including these topics. Especially, arrow functions, callbacks, promises, 'then' and Async/Await are used a lot these days.

It would make sense to add some of those, but not without big warnings to indicate that they are not supported by all major browsers in use today. But some of these would just make the tutorial too confusing for somebody who is just beginning.

We can add some of the topics mentioned in advanced topics. If we miss the latest/trivial topics (like Map & Set), then the students will miss out on concepts they should be aware of from the beginning. I have faced this issue in my career and would like anyone else to avoid this in future.
