Wednesday Workshops: Functional Programming Patterns in JavaScript

About

Each workshop is ~45 minutes over lunch on Wednesdays. There will be a repo with sample code and additional resources so you can continue learning outside the workshop if you want to.

Curriculum

We'll be using Michael Fogus' Functional Programming in JavaScript as a loose guide. I'll provide you with an electronic copy (EPUB, MOBI, or PDF).

Intro

• What is functional programming? (10 min)
• First-class functions (10 min)
• Applicative programming (15 min)
• Data thinking (10 min)

Scope and Closures

• Global vs. function scope (10 min)
• Lexical vs. dynamic scope (10 min)
• Closures (25 min)

Higher-Order Functions

• Functions that take other functions as arguments (10 min)
• Functions that return other functions (10 min)
• Example: building an object validator (25 min)

Building Functions for Fun and Profit

• Function composition (15 min)
• Partial application (15 min)
• Currying (15 min)

Recursion(-sion -sion -sion)

• Functions that call themselves (15 min)
• Functions that call functions that call back (15 min)
• Recursion, Iteration, and Stack Overflows (15 min)

Purity and Immutability

• Pure functions (15 min)
• Referential transparency (15 min)
• Immutability (15 min)

Flow-Based Programming

• You know this (it's Gulp!) (5 min)
• Chaining (20 min)
• Pipelining (20 min)

Classless Programming

• Wait, I thought we just got classes in ES 2015! (5 min)
• Data orientation (20 min)
• Mixins (20 min)

Bonus Round, 1 of 2: ClojureScript

• What is ClojureScript and why do I care about it? (10 min)
• Immutability by default (15 min)
• Programming without state (20 min)

Bonus Round, 2 of 2: ClojureScript

• Tooling (20 min)
• Debugging and workflow (20 min)
• Additional resources (5 min)
