If you need to use a specific dialect of lisp most people won't be familiar with, it does a poor job at it. Lisp is not a language many people use today. NeoVim lets you use any language you want for writing extensions. VS Code uses javascript which is easy to learn and most developers already know it.
It's a great strength that NeoVim supports many languages, and VS Code uses Javascript. Lisp is not widely used, and this is an impediment to Emacs' popularity. However, when people speak about Emacs customizability, they are referring to a deeper level of customizability than most programs (even NeoVim/VS Code), in which its innards and UI are all subject to modification, at runtime, within the beast itself. This is…
This is so unfortunate. Lisp has so many good things to teach us.
