This book shows JavaScript developers how to build highly dependable JavaScript projects using the Immutable.js framework.

Key Features

  • Master the Immutable.js JavaScript framework
  • Build predictable and dependable applications using immutability
  • Control how data flows through your application
  • Control the effects of data flow in your user interface using Node.js

Book Description

Immutable.js is a JavaScript library that will improve the robustness and dependability of your larger JavaScript projects. All aspects of the Immutable.js framework are covered in this book, and common JavaScript situations are examined in a hands-on way so that you gain practical experience using Immutable.js that you can apply across your own JavaScript projects.

The key to building robust JavaScript applications using immutability is to control how data flows through your application, and how the side-effects of these flows are managed. Many problems that are difficult to pinpoint in large codebases stem from data that’s been mutated where it shouldn’t have been. With immutable data, you rule out an entire class of bugs.

Mastering Immutable.js takes a practical, hands-on approach throughout, and shows you the ins and outs of the Immutable.js framework so that you can confidently build successful and dependable JavaScript projects.
