For a beginner, it is more advisable to start with the front end. The best way to get started is to start at the bottom of the page and work your way up.
I started with python as a teen, automating a bunch of things and helping with my homework. Went on to college for a CS degree and learned Java. Been there ever since and never had any interest on the frontend stuff!
