Im writing this just to show you how Memebrs-only posts are going to look like. 

Im going to add more items in to menu so it's easy for you to find the right category. Below you can find a content of one of my articles. 

Let's make it member only for this test. 

#### **Law 1**

- All Observables are lazy, without exception.

#### **Law 2**

- Observables are either cold, serving a single execution context per subscription in a unicast manner.
- Or hot, serving one or more subscribers with the same execution context, in a multicast manner.

#### **Law 3**

- Subject is both an Observable and an Observer
- The Observable part is multicast, but still lazily executed only when the first subscriber comes.
- The Observer part is the one created eagerly that allows us to call .next() and send data through the Subject;
- The Observer part does not imply that the execution context of the Observable is ‘alive’ before the first subscription is made.

#### **Law 4**

- There are stateful Subjects, like BehaviorSubject or ReplySubject, which extend the Observer part.
- Adding support for holding 1..n previous states, which the Observable part will multicast to potential subscribers.

By reading this, do you think that RxJS is a complex subject (pun intended :D)?

Angular Team announced plans to potentially make RxJS optional in the future.

Would you like to keep RxJS mandatory?

Or optional is the right way to go?
