This chapter is all about communicating progress to the user. React Native has different components to handle the different types of progress that you want to communicate. First, you'll learn why you need to communicate progress like this in the first place. Then, you'll learn how to implement progress indicators and progress bars. After that, you'll see specific examples that show you how to use progress indicators with navigation while data loads, and how to use progress bars to communicate the current position in a series of steps.
