Professor Frisby Introduces Composable Functional JavaScript by Brian Lonsdorf

• Create linear data flow with container style types (Box)
• Refactor imperative code to a single composed expression using Box
• Use chain for composable error handling with nested Eithers
• A collection of Either examples compared to imperative code
• Enforce a null check with composable code branching using Either
• Semigroup examples
• Create types with Semigroups
• A curated collection of Monoids and their uses
• Ensure failsafe combination using monoids
• Delay Evaluation with LazyBox
• Unbox types with foldMap
• Capture Side Effects in a Task
• Use Task for Asynchronous Actions
• Leapfrogging types with Traversable
• Maintaining structure whilst asyncing
• Build curried functions
• Applicative Functors for multiple arguments
• Apply multiple functors as arguments to a function (Applicatives)
• Write applicatives for concurrent actions
• List comprehensions with Applicative Functors
• Lift into a Pointed Functor with of
• Principled type conversions with Natural Transformations
• Apply Natural Transformations in everyday work
• Isomorphisms and round trip data transformations
• You've been using Monads
• You've been using Functors
• Build a data flow for a real world app
• Retrieve and use data from an api with pure functional constructs
• Find the intersection of sets with Semigroups
