Return break

[Msypon]

When we should use return and break?

return keyword is used to return one (or more) values from a function. break, as its name explicitly says, breaks a loop.

The return keyword should be used to return a value in a function, or stop it (simply use the keyword with no value). The break keyword is used to stop loops (do, while, repeat).

And for example:

break :

for i,v in ipairs{1, 2, 3, 4, 5} do -- looping table 
    if v == 2 then -- checking if the value is "2" while looping 
        break -- breaking/stopping loop 
        outputDebugString("Loop broken") -- outputs to debug 
    end 
end 

return :

function outputToChat(text) -- function you can call anytime you want 
    if text:lower():find("ixjf is nice") then -- if it found a similar word like this then 
        return outputChatBox("That's a lie!") -- it will stop the function from outputting the text and outputs this 
    end 
    outputChatBox(text) -- outputting to chat box the text message you've passed to the function 
end

Your break example is wrong, break has to go after your code inside the loop, like this:

for i,v in ipairs{1, 2, 3, 4, 5} do -- looping table 
    if v == 2 then -- checking if the value is "2" while looping 
        outputDebugString("Loop broken") -- outputs to debug 
        break -- breaking/stopping loop 
    end 
end
