Not easily. There is active work on compiler options, mainly around PackageCompiler and juliac, but there are a couple others, as well; you can look around on the forum for some of that. But nothing at the moment is going to be like, for example, Android Studio, Xcode/Swift, or mobile-centric web frameworks like Lynx.
It’s not impossible – people have gotten Julia to run on Arduino – but it’s hacky, and there are limitations. Cross compilation is also theoretically possible, but not easy. All of this should improve in the next couple years.
There is a Julia Language Slack.
