How to Get Started with Scala?
summary
Practical roadmap: use Coursier setup or Homebrew to install Java, Scala and Scala CLI, then try Scala CLI run/test/debug/repl on a single .scala file to get immediate results; use Metals (LSP) + a BSP server for editor integration, with Bloop as single-machine BSP server for lightweight multi-project work and SBT/Mill BSPs per workspace for heavier projects; expect Scala CLI 1.0.0 regressions to be fixed, Bloop needing refactor, debugging and test indexing still slow, and new actionable diagnostics with quick fixes and a toolkit (JSON, OS, HTTP, MUnit) to simplify dependencies.
