When to Choose Haskell

• Best for: correctness-critical systems | compiler-enforced purity | maximum type safety | financial systems
• Not ideal for: teams needing fast onboarding | rapid prototyping | .NET/JVM platform requirements

[STARTER] Quick Setup

# Install GHCup (manages GHC, cabal, stack, HLS)
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh

# Create project
mkdir order-service && cd order-service && cabal init --interactive
# Or: stack new order-service simple && stack build && stack test
