Where Could We Turn Up the Good?

Pure FP

• Elm 0.19 removing side effects
• Purity is what makes elm-review interesting
• Jeroen's post Safe dead code removal in a pure functional language
• No runtime exceptions

Useful error messages

• Evan's 2017 Deconstructconf talk Evan Czaplicki On Storytelling
• Evan's talk What is Success?

Having a single language flavor

• Isomorphic code
• Meta frameworks (elm-pages, Lamdera, elm-spa)

Decoupled tools

• The community can iterate quickly and experiment with new changes
• elm-optimize-level-2 and elm-format are great examples
• elm-optimize-level-2 can make their way upstream and don't break Elm's guarantees or assumptions
• Robin Hansen's blog post series Successes, and failures, in optimizing Elm’s runtime performance
• Extensible Web Manifesto
• Platform should provide building blocks, not solve every specific use case

Stable Core

• Stable data layer, architecture allows ecosystem to evolve around it with less churn

Community Members Working on What They're Passionate About

• People passionate about a problem working on it in the ecosystem

Performance

• Leveraging Elm's unique characteristics for performance (immutability, static language, known types, etc.)
• Elm compiler performance - compiler speed matters
