%% plugin
{
  "languageId": "lua",
  "displayName": "lua",

  "pluginType": "language"
}

%% js

for i=1,5 do
	print(i)
end

%%lua
-- run javascript console.log from lua
js.global.console:log("hello world")

%%lua
-- use javascript array in lua
t = {"foo", "bar", "baz"}
for k,v in pairs(t) do print(k,v) end

for f in js.of(js.global:Array(10,20,30)) do
	print(f)
end

%%lua
-- create variable to share with to js
local js = require "js"
local window = js.global
local document = window.document

window.foobar = 42

%%js
// use lua variable
window.foobar
