// This is a Jest spec that explores some of the different ways to alter
// arrays and objects without mutating state.  I'm trying different approaches
// available using:
//
// * Vanilla JS
// * Immutable.js
// * Lodash
// * Rambda
//
// The motivation for this is largely to work with a Redux store.
