Neither do I? It's just very embeddable so Roblox used it, there's nothing wrong with making Roblox games as a personal project as a way to learn, but just so you know, only as a personal project due to Roblox basically just flipping off new aspiring creators. Still, lua.org and lua-users.org are great ways to learn, as lua.org is an official website, and lua-users.org is on lua.org as a recommended resource. And if you are working with Roblox, you can also use https://create.roblox.com/docs/ as a resource.
