Google Maps, like any other Google product is already easy-to-use and their API is not that complicated to work with, BUT, things can always be simpler and GMaps.js, a feature-rich jQuery plugin, helps consuming Google Maps much easier.
Besides adding a standard map of a specific location, we can define the zoom level, add markers, get the location of a user (HTML5 geolocation), define routes, draw polylines and more with only few lines of code.
