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

## Trend changes rapidly

In web development, the trends tend to change rapidly. That's a good thing for improving technology, but it's hard for learners.

Fortunately, the React documents are improved and up to date. My recommendation is to check out [the official documentation site](https://reactjs.org/docs/).

## Enjoy coding

A final word: Enjoy coding. That's it.
