Default Arguments

During a function declaration, parameters can now declare their own default value.

Example Code

local function write(text = "No text provided.")
    print(text)
end

write()         --> "No text provided."
write("Hello!") --> "Hello!"

This code behaves identically.

local function write(text)
    if text == nil then
        text = "No text provided."
    end
    print(text)
end

write()         --> "No text provided."
write("Hello!") --> "Hello!"
