Their documentation is always so up-to-date, and easy to discover too! I've never once searched for something, only to stumble onto a page of docs that's 3 years old and no longer relevant. Nope!
They take the most direct way of explaining things too, instead of always going in a roundabout way. Their design decisions do not leave anything to be desired and you're never left scratching your head as to why anyone would ever build something this way especially when there are dozens, dozens of people asking for it to work the way any sane human being would think it should work. Great for kids!
