Eric Elliott's "Composing Software" Series

A collection of links to the excellent "Composing Software" series of medium stories by Eric Elliott.

Edit: I see that each post in the series now has index, previous and next links. However, they don't follow a linear flow through all the articles with some pointing back to previous posts effectively locking you in a loop.

• The Rise and Fall and Rise of Functional Programming
• Why Learn Functional Programming in JavaScript?
• A Functional Programmer’s Introduction to JavaScript
