That's an apples to oranges comparison...

F# and C# compile to the same intermediate language, are interpreted on the same runtime, and are produced by the same organization for the same IDE... Their libraries are compatible and they rely on shared access to the common .net ecosystem.

Your absolute worst case scenario would involve decompiling your F# source as C#. More realistically you would use dependency management to gracefully transition out of one of the languages.

Transitioning piecemeal works exceptionally well: it's exactly how I've transitioned numerous projects away from C# onto F# ;)

Ummm Purescript compiles to JS and shares the same runtimes. Both languages have support from popular text editors, and their libraries are compatible and rely on shared access to the common JS ecosystem. In what way is it an apples-to-oranges comparison?
