Concepts

The main concepts are:

Store is observable object created from any valid JavaScript object.

Any part of the store is also a store

Reaction is a function that can use values from store.

It is supposed to be called again in response to changes in the store it was reading from during previous call.

Act of automatically or manually running reactions in response to store changes

Selectors allows us to perform some expensive calculations or async requests and reuse the results multiple times.

If selector reads from any store - it will automatically re-calculate it's value after related store values are changed

React specific

View is special kind of react component that will automatically re-render itself if any store value it used during the render changes

React re-render could also be called reaction if used in context of react & statek.
