Vue is a pretty big deal in the PHP/Laravel community. Evan the creator even gave a talk at Laracon a few months in, showing the hockey stick growth after it started to get traction in the community.

True. Though I also expected to "Reactistan" somewhere more explicitly, I wonder if it is scattered in Fronterra continent?

I am also puzzled myself why the algorithm has separated Fronterra from another large island to the west, seemingly related to node and some other JS libraries. Decided to keep it all as is in case I'm missing some reason

My feeling is that the React community is at least double to triple the size of the Vue one, so yes, I feel React should definitely be it's own island.
