What languages deploy and are also themselves standalone executables?
Some examples:
* Red (might be wrong about this one)
* Deno
* Godot
If your goal is just to produce a single file that is equivalent to a large number of files and a single executable, I would suggest you look at AppImage(https://appimage.org/) you can make almost anything into an AppImage from any language, although it is not always easy to setup(check out the packaging guide https://docs.appimage.org/packaging-guide/index.html).
> The key idea of the AppImage format is one app = one file
From the website
Can you define "standalone" executables and "deploy"? They can mean different things depending on context, for example if you mean a single statically linked executable (rare) or an application bundle that packages dependencies, etc
Factor fits what you're asking for, I think. It doesn't seem to be all that common for compiled languages to be designed "monolithically" with IDE and compiler as one package.
