So I was talking to a friend and he mentioned
and there is this programming language that lets you write code that is multi-platform:
I was wondering why these hasn't got that much attention yet because the idea is so good.
So in a sense, what is probably wrong with these ideas in a real-world perspective(real deployable projects)?
EDIT: So I have probably misused some terms so here are some clarifications. It goes something like, for example, I write code in one language, then I can run it in iOS and Android devices, both of which have their native programming languages. That means I have an app that I can run on both device without having to code any Java or Objective C That's the best I can do for clarifications because I myself am a little confused T_T
