Mastering Immutable.js

Chained operations are easy to understand

When you chain data transformation operations together, it's easy to examine the code and get a sense of what the end result will look like. With Immutable.js sequences, we get to keep this easy-to-maintain code structure, while sequences handle the underlying lazy evaluation. You don't have to think about passing individual collection values from one operation to the next—this all happens seamlessly.
