I'm glad there are ways to make it work with gsap, but I don't see the points Jack made being questioned.
I agree about the react "way of thinking" being more pleasant to the developer tho: inmediate mode, you don't have to think too much about edge cases, etc. But it comes at a price and with its own set of drawbacks.
Anyway I hope someone can post some examples, performance comparisons, etc, so we all can get a better understanding of all the particularities.
