lua - how to create functions

Question

I have a question about declaring functions in lua.

I was under the impression that public functions are declared as:

abc = function()
end

Local/private functions as:

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 manual ,

The statement

 function f () body end

translates to

 f = function () body end
