I might be ‘doing it all wrong’, but in a sequence of animations, at one point, during the run of the animation i.e. at a point between start and end of an animation timeline, I’d like to fire off some javascript, which, in turn, will cause some other animation to start, but only when the jSON has been received and parsed from that first javascript call.
Then in the function that is fired you have your json GET/Fetch that on success uses one of the javascript Timeline APIs to run the the timeline with the next animation.
