Thanks to this article, I learned that the core data structure for VSCode's text is written in TypeScript[0]. I, uh, I knew VS Code was written in TypeScript but I didn't realise _all_ of it was. It's scary that the editor works as well as it does!

  View Large Files in Emacs

That is essentially what VLF[1] does in Emacs. It reads in discrete chunks of the file at a time and doesn’t load the next one till you try to display it. Doesn’t require any fancy data structures, just some extra book keeping and mechanics.

It’s backed by a “vector of vectors” data structure called a relaxed radix balanced tree:
