# Conan State

Conan State are capsules of state that can be reused. To learn more about how to manage data in ConanJs, have a look at our [General Concepts section](https://docs.conanjs.io/data/general-concepts)

{% hint style="warning" %}
A convention used across the documentation, and that we invite you to use (but is not mandatory) is to suffix your Conan State name with a $. ie todos$
{% endhint %}

**You interact and define your Conan State with reducers and actions**

{% content-ref url="conan-state/actions" %}
[actions](https://docs.conanjs.io/data/conan-state/actions)
{% endcontent-ref %}

**If you understand the concepts behind the actions and reducers, then you are ready to see how to create state**

**Subscribing to state will show you how to render your state either by connecting to your own components, or via live rendering**

**With Conan, you can create small Conan State elements which will be easier to test, develop and reuse. Then, you can compose new state based on this atomic states.**

**Not all state should be global, or in the context, or local.... With ConanJs you can easily decide how to scope your state**

**It is also possible to create interactions between Conan States, for this, you can leverage the reactions**

**Error handling is built-in to make your life easier...**
