When comparing MS PowerShell vs Elixir, the Slant community recommends Elixir for most people. In the question“What is the best programming language to learn first?” Elixir is ranked 9th while MS PowerShell is ranked 64th. The most important reason people chose Elixir is:
Leverages the existing Erlang BEAM VM

Pros
Pro Helpful Help
The help system is designed to evolve over time; running update-help
downloads the latest content.
When searching for help on items, you can simply type help commandname
to get information about a command.
If you're not sure what you're looking for, but have a rough idea, you can search on partial command names, or even specify specific verbs to get a list of commands potentially of interest; e.g. help -verb write
.
The information in help gives a good overview of the commands you're looking at, along with code examples, so you can see real-world usage without resorting to the web.
Pro Splatting
When calling a method with multiple parameters, rather than passing one variable per parameter you're able to "splat" one variable to the method, with the parameters taking their values from its properties.
Pro Pipeline
Commands can be chained via the pipeline, allowing output from one to be cleanly fed as input to the next.
Pro Chocolatey Package
PowerShell is installable through Chocolatey.
Pro Extensible
The language can wrap and interact with code written in other language's, making it highly extensible.
Pro Multi-Platform (ish)
Though Windows Powershell only works on Windows, the open source implementation Pash (http://pash.sourceforge.net/) allows the same language to be run on other OSes.
Pro Great for concurrency
Leverages the existing Erlang BEAM VM
Pro Great getting started tutorials
The tutorials are very clear and concise (even for a person not used to functional programming). Plus they are also very mobile friendly.
Pro Powerful metaprogramming
Write code that writes code with Elixir macros. Macros make metaprogramming possible and define the language itself.
Pro Full access to Erlang functions
You can call Erlang functions directly without any overhead: https://elixir-lang.org/getting-started/erlang-libraries.html
Pro Scalability
Elixir programming is ideal for applications that have many users or are actively growing their audience. Elixir can easily cope with much traffic without extra costs for additional servers.

Pro Great as a first functional programming language!
Pro Great documentation
Elixir's documentation is very good. It covers everything and always helps solving any problem you may have. It's also always available from the terminal.
Pro Syntax is similar to Ruby, making it familiar for people used to OOP
All of the benefits of Erlang; without as steep a learning curve of prolog based syntax. Elixir is heavily inspired by Ruby's syntax which many people love.
Pro Easy to download libraries
Comes with built in build tool called "mix". This will automatically download libraries and put them in the scope of the application when you add them to the "deps" function and run mix deps.get
Cons
Con Very verbose
The commands themselves, as well as the output and error messages, are VERY verbose
Con Deployment is still not as easy as it should be
Con Some design choices may seem strange
Some design choices could have been a little more appealing, for example: using "do...end" comes natural in Ruby for blocks but Elixir uses them for everything and it looks pretty weird:
Enum.map [1, 2, 3], fn(x) -> x * 2 end
or
receive do
{:hello, msg} -> msg
{:world, msg} -> "won't match"
end
