A Whirlwind Tour of PureScript • Rob Howard • YOW! 2016

PureScript is a strictly evaluated, strongly typed functional language inspired by Haskell that compiles to JavaScript

Key language features include:

• Row types for flexible record typing
• FFI (Foreign Function Interface) for easy JavaScript interop
• Effect tracking through the Eff type
• Pattern matching
• Type aliases and type safety

The Pux framework provides UI architecture similar to Elm:

• State management through pure update functions
• Actions trigger state changes
• Views are pure functions of state
• Supports side effects through Eff

Development workflow uses:

• Bower for package management
• CommonJS modules for JavaScript integration
• PSCI for REPL development
• Property-based testing through QuickCheck

PureScript emphasizes:

• Pure functions without side effects
• Composition of functions
• Strong type safety
• JavaScript interoperability
• Partial functions must be explicitly marked

Learning resources available:

• PureScript book (free online)
• Documentation site with tutorials
• Workshop materials
• Example applications
