This repo is for people who are mostly familiar with JavaScript to work through the Martin Fowler article Refactoring with Loops and Collection Pipelines. The problems.js file contains the initial code before each refactor. The solutions.js contains my solutions to the problems for comparison. The tests.js file contains tests that ensure that refactors do not break the public interface of the functions.
