I tried to make all Vim builtins also ES builtins so that simple scripts look almost the same in ES as in Vimscript. Have a look at https://github.com/bobpepin/vim/blob/duktape/runtime/indent/python.js, autogenerated from the corresponding .vim file, https://github.com/bobpepin/vim/blob/duktape/runtime/indent/python.vim.

(Caveat: no datatypes requiring automatic memory management can be passed between Vimscript builtins and ES)

I am playing around with the asyn/await features from recent ES versions together with Vim channels and events (keyboard input/autocmds) right now, imho it's significantly more effective than Vimscript as soon as callbacks get involved. For a sample JSP implementation, see https://github.com/bobpepin/vim/blob/duktape/src/jsp-jsonrpc.ts.

Best,
Bob
