React Tracked is a small library for global state with React Hooks and
React Context. It allows you to develop a small web app with global state
without a bigger library like Redux.

In this course, you will create a to-do app. But before diving into
creating an application, you’ll first learn how React Tracked can solve
common performance issues around render optimization. Once you learn how to
work with this library, you’ll then build a to-do app through two different
methods.

By the end of this course, you will be ready to build more advanced
applications without having to do unnecessary re-rendering. You’ll also
have a nice piece to showcase in your portfolio.

React Tracked: Creating Web Apps with Global State

## Things we can learn from Redux

Redux is a small library, but its ecosystem is huge. Even though we don’t use Redux directly, it helps us. The Redux ecosystem provides various best practices, documents, utility libraries, and so on. React Tracked is influenced by Redux, and lots of knowledge in the Redux ecosystem is applicable to React Tracked.

Check out the [Redux Style Guide](https://redux.js.org/style-guide/style-guide/), for example.
