Basic Concepts

• Pros and Cons of Using Immutability With React http://reactkungfu.com/2015/08/pros-and-cons-of-using-immutability-with-react-js/ Excellent description of what immutability is, how to use use these concepts with React, and pros and cons of managing data immutably. While the title refers to React, most of the writing just deals with plain Javascript concepts.

• Javascript and Immutability http://t4d.io/javascript-and-immutability/ A description of how to properly immutably update objects and arrays using functions like assign and slice

• Immutable Javascript using ES6 and Beyond http://wecodetheweb.com/2016/02/12/immutable-javascript-using-es6-and-beyond/ Describes ways to handle data immutably using "just" built-in Javascript functions, particularly ES6 syntax

• Pure javascript immutable arrays http://vincent.billey.me/pure-javascript-immutable-array A reminder to avoid the built-in Array functions that mutate the array, with snippets demonstrating alernative immutable functionality

• Javascript Array: slice vs splice https://ariya.io/2014/02/javascript-array-slice-vs-splice A reminder that "slice" and "splice" are different functions with different behavior

• Immutable Data from Scratch https://ryanfunduk.com/articles/immutable-data-from-scratch/ Demonstrates building up an immutable update utility library similar to React's Update Addons

• Immutable Objects with Object.freeze http://adripofjavascript.com/blog/drips/immutable-objects-with-object-freeze.html A quick look at how to use Object.freeze to enforce immutability.

• Immutability in Javascript http://www.sitepoint.com/immutability-javascript/ Describes a couple basic concepts of immutable data in Javascript, and how the Immutable.js library can be used for those concepts.
