Interactive Shell

One of the easiest ways to execute Elixir commands is by simply running the iex command on Linux and macOS, or iex.bat on Windows, since the iex command there is a PowerShell command in the terminal.

IEX stand for Interactive Elixir

$ iex
Erlang/OTP 27 [erts-15.1.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit:ns]

Interactive Elixir (1.17.3) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>

Note	To exit the Interactive shell just press CTRL+C twice.

Examples of Interactive Shell

iex(1)> 1 + 2
3
iex(2)> 1.1 + 2
3.1
iex(3)> 6 / 2
3.0
iex(4)> IO.puts("This is a text")
This is a text
:ok

Note	The :ok is a common convention in Elixir and Erlang to signify that a function has completed without errors. It can be useful for confirming that an operation, such as printing to the console, has been executed properly.
