Not quite the same. But I guess in Emacs you can have code alongside text alongside images and graphics for pretty much any programming language. Another related concept is literate programming. There comments and code kind of switch roles. The comments (i.e. text) are the primary content and the code is designated (but still executable). I feel like it went a bit out of fashion, but a more modern application of this is ZX markdown scripts: https://google.github.io/zx/markdown-scripts https://google.github.io/zx/markdown-scripts Those are markdown files with JavaScript code blocks. The entire file is executable.
