I'd say Ruby and Lua are slightly easier, but when you start out with programming the language isn't really the problem, it's the basic programming concepts that you find in all programming languages like variables, functions, loops and so on, once you got those down you can pick up any language with enough time and willingness to learn.

The biggest problem there is perseverance, you need to really want to learn programming so that you don't give up, so it's best to find something you want to create that you're really passionate about so that it keeps you interested. If you're into games, check out Colobot which is a free game that teaches you programming, you're an astronaut visiting different planets and you program robots to help you solve tasks. There's also Pico-8 which is a complete development environment for creating little old school games like Tetris which is very easy to get into.

The app downloads videos from a few hundred websites, including YouTube :) The youtube-dl website has a list of supported sites.

Thanks for your kind words!
