Updates to the homepage - add new tagline, why scala? and use cases

[bishabosha]

This is the next step in modernising the Scala homepage.

We simplify the large opening paragraph, splitting it into three new paragraphs that better communicate the same message, and add more detail.

We also add a new "use cases" section, which is based upon what was reported in the Scala Developers Survey 2022. This section could potentially be continuously evolved as developments unfold.

The "Scala in a nutshell" section is removed - we felt that the examples were outdated, and now we have the carousel of code snippets to better showcase the "flavor" of Scala.

Thanks to everyone at the Scala Center and LAMP who assisted in validating the design and suggesting content.

Thank you! I only have minor comments.

This snippet is a bit conflicting. Node.js and serverless are not frontend web technologies. Actually, the point is that you can use Scala.js very effectively on the server-side, where its fast and lightweight runtime can be advantageous over the JVM for some services. Further reading.

Thanks, I can see that it makes sense what you say - I think I can keep all mention of node.js to the server-side section

@armanbilge This is a good point! Slightly related to that, the last point of the “Command Line” section mentions compilation to native binaries. I wonder if we should capture the multi-platform aspect of Scala in a separate section (outside the “Frontend Web” and “Command Line” sections)… Or maybe we could just move the sentence about Node.js into the “Server Side” section and keep the “Command Line” section as it is?

(I'll review next week.)

Yeah, it's very difficult to present this aspect of Scala :) rather than present platforms as independent features, I think it's helpful to present them under the use cases where they are most relevant. Actually, all platforms could technically be used in most/all domains (except frontend, that's effectively JS-only), it's just there are certain use-cases some platforms can excel at.

servers: Scala JVM
serverless: Scala.js (and Scala Native, but ecosystem is still maturing)
data processing: Scala JVM (and one day Scala Native could excel here)
command line: Scala.js or Scala Native or Scala JVM with Graal Native image
frontend web: Scala.js

@armanbilge I changed the frontend section to avoid mentioning node.js

Looks great :)

@SethTisue did you get a chance to look?

[SethTisue]

This is fantastic. Well done!
