How is the "connection" of languages ​​​​when creating a game?

Question

Programming

Very often I saw something like such phrases "The game is written in C ++ and UI on AS (Flash)" How so? And not only games, a lot of any projects are written in completely different languages. Another example is "Game in C++ and AI in Lua"... In general, I don't understand how it's done... Can you please explain?)
