Use my branch/fork; repl can be found at https://daurnimator.github.io/lua.vm.js/repl.html

When a Lua variable is exposed to javascript; it is exposed as a function object; with methods invoke/get/set/etc. See https://github.com/daurnimator/lua.vm.js/blob/master/lua.js#L523

Using your example; expose the object to javascript somehow. e.g. in lua:

window.mydata = data
window.mykey = key

Then in javascript:

v1 = window.mydata.get(window.mykey)
v2 = window.mydata.get("a").get("b")
console.log(v1)
console.log(v2)
