Lua - how to create functions

Question

I have a question about declaring functions in lua.

I got the impression that public functions are declared as:

abc = function() end 

Local / private functions:

 local abc = function end 

But I'm not sure what this notation is:

 function abc() end 

Answer 1

As seen in 2.5.9 of the reference guide

Statement

  function f () body end 

translates to

  f = function () body end
