[Doubt] local function and function

[Mature]

Hello community, I have the following question, what is the difference between a local function and a function?

Example:

local function ()

For this

function ()
  

When should I use a local function and when should I use a common function?

A local function is just the function value saved inside of a local variable.

 

---

 

Like this (a local available before the function is defined):

local test

function test ()
  
end

 

or this (a global, as well as a local after the local keyword):

function test ()
  
end

local test = test

 

or this: (a local variable, available after the function)

local test = function ()
  
end

 

or this: (a local variable, available in and after the function)

local function test()
  
end

 

So when do you need to use it? The same way as just a regular local variable.

• Variables that are accessed a lot of time. (onClientRender)
• Variables that are only available within it's scope.
• Variables that are temporary required.
• etc.
