Location-based services are a very useful capability and, from what we've learned in this chapter, we can create our very own service by integrating the three examples we've featured. We can create search or directory services that allow users to find establishments and give them easy access to directions to get there from their location that we can also retrieve using the geolocation example. In the next chapter, we will understand how PhantomJS allows us to read and write files using its own FileSystem API.
