When we start working with React components, we frequently hear two terms. These are `state` and `props`. So, in this article we will explore what those are and how they differ.
## State:
* State is something that a component owns. It belongs to that particular component where it is defined.
For example, A person's age is a state of that person.
* State is mutable. But it can only be changed by the component itself, meaning it is private. As I only can change my age, no one else can.
* You can change the state by using `this.setState()`
