This chapter covered almost every major topic required to create a Leaflet map. You learned how to add tile layers from multiple providers, including satellite imagery. You can now add points, lines, and polygons to the map, as well as collections of polylines and polygons. You can group layers of different types into layer or feature collections. This chapter covered the styling of objects and adding pop ups. You learned how to interact with the user by responding to events and created custom functions to allow you to code more by writing less.
