Immutable.js

Again, utilizing immutability, we can code in an easier-to-understand fashion. However, it will usually mean we can't scale to the levels that we need for truly high-performance applications.

First, Immutable.js takes a great stab at the functional-style data structures and methods needed to create a functional system in JavaScript. This usually leads to cleaner code and cleaner architecture. But, what we get in terms of these advantages leads to a decrease in speed and/or an increase in memory.
