Someone please differentiate between these 3 type of script?
Can someone please tell me the difference between a Script, LocalScript, and ModuleScript?

Local script: "A LocalScript is a Lua source container that runs Lua code on a client connected to a W server." - Roblox Wiki
Module script: "A ModuleScript is a Script-like object that contains code for a module." - Roblox Wiki
Normal Script: "A Script in ROBLOX is a type of object that holds a section of Lua code. A script will execute on the server and has access only to server-side events and properties." - Roblox Wiki

You should research into Robloxs' Wiki time to time.
Heads up! If you learn to code in other languages, you will need a more detailed explanation of threads, environments, and other stuff that makes the differences between these scripts HUGE.
Since the other answer did not do a great job I'll try to be as vague as possible
LocalScripts can only run on the client side, meaning they can't urn in workspace unless they're inside of the character
Scripts can be run on any Server managed area. This means it's mostly used for server-side interaction, but cannot use things like game.Players.LocalPlayer
ModuleScripts are scripts that do not autorun, so at the end of the script you have to return something that can be called
Example
Inside the module script
local thing = 3
return thing
Inside the Script or LocalScript
local module = require(Place where the module is located)
print(moduld) -- prints 3
