Haxe's transpiling helped me in a project once. The client needed a small-ish web app written ASAP, but they didn't know anything about their backend/stack when asked since they were non-technical and using an external provider for everything. The provider was not responding to emails for some reason, and the deadline was approaching, so I decided to start writing the thing in Haxe.
I figured they were either running PHP/SQL or Node, so I wrote a simple backend in a way that would make it easy for to deploy to either one with minimal changes. By the time the provider finally replied, the project was nearly half way complete. It turned out that they were using a standard PHP/SQL stack, so had I gone with Javascript there would've been problems. Instead, all I had to do was change one flag in my build system.
I don't know if this is a big selling point for Haxe since it's such a highly specific situation... but it's probably at least worth mentioning :P
