Arduino Sketches In BeagleBone Black

Hi, I am an arduino uno user, and am planning to buy BeagleBone Black in a few weeks. But as I far as I have learned, the programming in BBB is not the same as arduino. Being comfortable with arduino, I was wondering if it is possible in any ways to use the exact arduino sketches in BBB?. I have googled a lot and it happens to be possible as stated in adafruits website, but is there a simpler method?. It would be of great help, if someone could assist me.
