Like most other programming languages, Elixir has a concept of variables. Variables are, simply put, just a place to store values or data.

We can declare a new variable as simply as follows:
iex(1)> greeting = "Hello There""Hello There"
In IEx, the output of any statement entered is always the next line in the shell.

iex(2)> greeting"Hello There"
While variables can be reassigned in Elixir, ...
