I am looking to code for Hulu. where should I start learning?

That depends what spectrum you would like to go into. First research and see if you can find if hulu used web apps, mobile apps, or a combination of both. That should give you an idea of what languages they use. After that, see if you're interested in one of the languages over the others, that could give you a slighter advantage to learn it faster if you're more inclined to learn in the first place. After that, see if treehouse teaches it. If you go through the treehouse courses, maybe try codefights, codecademy, and any other useful lessons on youtube you come across. This should give you an edge over other people trying to work at a place like hulu. Remember, knowledge can get you far, but being able to simply stand out from the rest of the bunch can make a bigger difference.

Thanks for feedback.
