React State Array: Updating An Array That Is Stored Inside Of State

State is one of the most important concepts in React. It’s what allows us to build components that manage and maintain their own data, and it also enables us to create reusable components that can be shared across projects without duplicating code. But what exactly is State, and how do we use it? A component’s state is simply a JavaScript object with properties and values. The values of these properties can be changed over time (hence the name “state”) by invoking setState().
