Proper Documentation and easy implementation

Leaflet application is quite user friendly and simple compared to the other JavaScript applications. The application size is small which doesn't occupy much space. I have been using this software when I used to work for Evernote and now while working for University of Cincinnati. The mapping area shown on the application is quite helpful. I used it to develop the night ride application in the University of Cincinnati.
