Modules

A module is a collection of One (1) or more relatable functions.

Defmod

To assign a name to a module, use the defmodule construct to create a module, as follows:

defmodule TopMod do

The Do End Statement

When constructing a function in Elixir …

You may use the basic Elixiritive-function template, as follows:

do
# This is the body of an Elixir function
end

Note. Elixir functions can be placed in an (.exs) file and executed sequentially via the Terminal prompt by simply “calling” the name of the page, as follows:

elixir page_name.exs

Returns,

"Hello Elixirites!"

Modules

Modules in Elixir can be used to segregate the one or many functions of your program.

By placing “like” functions in their own namespace or module within your program, the readability of your code is enhanced.

Macro Defmodule

In Elixir, a namespace that invokes the macro defmodule is called a module of one or more functions and can be created using the following syntax:

defmodule name do
# Place your functions inside this `do - end` statement to create a module
end

;where the variable name identifies the module explicitly

and,

;where the variable name can include one or more underscore, as follows:

defmodule name_your_module do
# Place your functions inside this `do - end` statement to create a module
end

Scope

Note. Variable names given to modules cannot be invoked from outside the module.

In other words, entire modules full of functions cannot be “called” from outside the module like a single function can be called in Elixir.
