# Redux

Tool · [Standard tools and platforms](https://ecosystem.samcarlton.com/tools)

Also called: Redux Toolkit, React Redux

A [JavaScript](https://ecosystem.samcarlton.com/javascript) library for keeping an app's shared data, called state, in one place, so every screen shows the same information. It is often used with [React](https://ecosystem.samcarlton.com/react).

**For example:** A [developer](https://ecosystem.samcarlton.com/software-engineer) stores the shopping cart in Redux so the cart badge and checkout page always agree.
