BASIC example on gsub

local text = "Hella Warld"
text = string.gsub(text--[[the string]],"a"--[[character to replace]],"o"--[[character to replace with]])

BASIC example on split

local text = "Hello World! Welcome to the universe!"
print(string.split(text--[[the string]]," "--[[splitting string]]))

Split
Lets say you want to have a command on chat, and you want to have this format :
command target

Using Player.Chatted , you’ll use split to get those separate words, e.g:

game.Players.PlayerAdded:Connect(function(Player)
  Player.Chatted:Connect(function(Message)
      local split = Message:Split(" ") --- between the "" put the symbol you want to segregate the words with. 
      if split[1] == "!kill" then
         if game.Players:FindFirstChild(split[2]) then
            game.Workspace:FindFirstChild(split[2]).Humanoid.Health = 0
         end
      end
    end)
end)

Gsub
Let’s say you have a message that you’d like to replace each time.[ A minigame intermission message can be an example].

local IntermissionText = "Round ends in 10 seconds"
local newText = IntermissionText:gsub("%d","#")

print(newText) -- will print 'Round ends in ## seconds'

Conclusion:

Split

Returns a table of strings. Very useful with admin commands. In the ("") you’ll need to provide any symbol that’ll segregate the strings.

Gsub

Replaces any provided key[string/number,etc] by the provided replacement.
