This is exactly why I would learn it. It's exactly how I've learned (in depth) ALL of the 10-15 various languages I know. Start with something that's familiar and work backwards.
I hate the bullshit elitist crap like "oh don't learn that, you can't code in Go until you've learned x,y,z". Everybody learns differently. I learned jQuery before learning JavaScript.
I wish the people on this thread would stop assuming everyone is clones of them.
