In this chapter, you learned about how to show your users that something is happening behind the scenes. First, we discussed why showing progress is important for the usability of an application. Then, you implemented a basic screen that indicated progress was being made. You then implemented a ProgressBar component, used to measure specific progress amounts.
Indicators are good for indeterminate progress, and you implemented navigation that showed progress indicators while network calls were pending. In the final section, you implemented a progress bar that showed the user where they were in a predefined number of steps.
In the following chapter, you'll see React Native maps and geolocation data in action.
