local json = require("json")

local tb = json.decode(jsonstr)
table.insert(tb.a,"hello world")
print(getmetatable(tb.a))
print(json.encode(tb))--{"b":{},"a":{}}
print(json.encode(tb,{empty_table_as_array = true}))--{"b":{},"a":{}}

This should work:

local json = require("json")
local t = {a={},b={}}
local jsonstr = json.encode(t, {empty_table_as_array = true})
local tb = json.decode(jsonstr)
table.insert(tb.a,"hello world")
