Hi, I am @Grass_dev.
The popular game engines used some json scripts to keep some important data of games ( level, coins, gems )
I know, lua is good to keep data, but I think the json better than lua in keeping data. fix it.
what is the differents between json and lua scripts when keeping data?
Lua was created as a configuration language and it is excellent as a way to store data, but JSON has a much wider use.
Come on! This really comes across as very rude. What do you expect will happen when you write “fix it”? That we drop everything we are working on and make this our top priority?
I suggest that you start by looking through our API: API reference (go)
If you had done that you would have noticed that there’s already a json.decode() function to translate JSON data into Lua: API reference (json)
And if you Google “json to Lua” (Google Search) you’ll see that the first search result is this excellent pure Lua implementation of both JSON encode and decode: GitHub - rxi/json.lua: A lightweight JSON library for Lua
JSON is not a scripting language like Lua is. JSON is a data container format. We use JSON in our projects to hold some kinds of data such as localization or definitions (and use the mentioned json.lua to interact with JSON files), but I prefer using Lua tables when I can. When you use sys.save() or sys.load() you are saving/loading directly to Lua tables.
I tend to favour lua over json. They are more or less the same.
I have run into a situation where I had to use json, because I had more than 27000 entries, and for some reason that was crashing the html5 build (not the desktop or mobile). Converted to json and it was working on all the platforms with no issues. This is another story though 
For big data Lua is much more preferred, because there is no decoding involved as with JSON, therefore your game can load much faster.
okey, thanks for all who help me…
