Youtube is junk if you're just starting out learning theory. There is no curriculum. You watch a video on scales....and then what? Okay, I think I need to learn chords...watch a few videos on chords-oh wait, what are intervals? How do chords come from scales...damn, gotta find a video on that...what are modes?...I'm confused, how do make music with chords? what are chord progressions......There's this youtube thing now. Should give it a shot.
I never even considered a book when it comes to theory, its already boring enough as it is in my opinion. There are good video series on youtube if you just look. But hey it doesn't really matter anyway, if you do books you do books. Im just assuming based on your last posts though that you haven't done a ton of research and it actually might be legitimate to assume you really don't know youtube has music theory on it haha, No offense.
Plus theory is tricky too so it might actually take looking at multiple sources/perspectives of it to have certain parts of it click. Id check out the youtube videos regardless, at least while you wait.

And on it goes 'til you either get fed up with it, or decide to actually try learning how to understand this stuff in an logical, organized fashion. Meanwhile, you never really learned how to apply any of what you "learned", so you don't get why certain basic concepts are important or how to use them musically. You want proof? Check out the theory section of this site. How you gon' make sense of modes if you don't understand how to spell a major scale?
People give YT way too much credit as a learning tool but neglect to mention that the one thing YT videos won't give you is CONTEXT. Most YT tutorials are hit and run style affairs--give a brief overview and the rest is up to you to figure out. Its like trying to learn basic math from the Mathematics section of the library-sure, all the knowledge is there, but how you gon' sort it all out?
