Best place to learn LUA scripting?

Hello everyone, I am fairly new to scripting/coding in Gmod. I've used plenty of hacks, and I've gotten kind of bored of using someone else's hacks. So, I thought, maybe I should start learning to script using LUA, and eventually learn to make my own hacks. What do you think the best place is to learn how to do this? I have basic knowledge of Java coding, but not much else. I'd just like to know what people in this community did to learn how to do it, and eventually I hope to be able to start making my own scripts. Everyone has to start from somewhere, right?

On youtube, search up "MrCosmicSeagull Garry's Mod Lua Tutorial | 1"

Watch his play list. This is how I learned.
