In light of the fact that the "PETE" stack having Two Programming Languages,
some people feel "stuck" with the question: "which one should I learn first?"

This is a good question and I feel it's worthy of having a detailed discussion to help people understand that there isn't a "right" or "wrong" answer; only the answer that "works" for you.

Both Elm and Elixir are "complete" languages that allow us to build entire apps.
I would recommend that people get a "taste" for both languages but depending on the type of app you are building, pick one to focus on. For example, I am building an app that relies on "Time" in the browser to display a clock in the browser, therefore Elm is my only option1. And that is the same for all Apps that require a "rich" user experience.

Focus on Elm and build a rich user experience.
If you need to persist data, post a comment below and I will help you get started!

1Note: Yes, I know this is going to be possible in "Phoenix LiveView" #68 but until that is released as "Alpha" I have to use a front-end tech for building my client apps. Also, "LiveView" will require server-side re-rendering, I want the app I'm currently building to be an "offline first" PWA.

Does elm allow someone to have PWA on the same app?

@sigu good question. ❓
For now, there is no official way of doing server-side rendering with Elm.
So any App written in Elm is a client-side only App, i.e. Not a Progressive (Server-side Rendered) and client-side enhanced App.
This is why we use Elixir for our Server-side programming language (all our apps are rendered on the server) and then enhanced on the client.
In some cases we build our "backend" as an API and do all rendering on the Client,
but we prefer to build PWAs because sadly the client (browser) is not 100% consistent.
We still encounter users with Internet Explorer or JavaScript disabled.

To simplify our stack, we've (reluctantly) removed Elm and instead are using LiveView as part of PETAL #87
