Immutable.js State Management

#What is Immutable.js?

Immutable.js is a library for JavaScript that provides immutable persistent data structures. It allows you to create objects that are immutable, meaning that they cannot be changed once they are created. Immutable.js is a functional programming library that helps developers write code that is easier to reason about and more reliable.

#Immutable.js Key Features

Most recognizable Immutable.js features include:

• Immutable data structures: the library provides a set of immutable data structures that can be used to create and manipulate collections, maps, lists, and more.
• Persistent data: the data structures created by Immutable.js are persistent, which means that when you make changes to them, the original version is not changed. Instead, a new version of the data structure is created, with the changes applied.
• Performance optimizations: Immutable.js is designed to be highly performant, with optimizations such as structural sharing, memoization, and lazy evaluation.

#Immutable.js Use-Cases

Some of the Immutable.js use-cases are:

• Managing state in React applications: Immutable.js can be used to manage state in React applications, making it easier to reason about and preventing bugs caused by unexpected mutations.
• Data modeling and processing: the library’s data structures are ideal for modeling complex data and processing large data sets efficiently.
• Caching and memoization: Immutable.js can be used for caching and memoization, improving performance by avoiding unnecessary computations.

#Immutable.js Summary

Immutable.js is a library for JavaScript that provides immutable persistent data structures. It is a functional programming library that helps developers write code that is easier to reason about and more reliable, and it can be used for managing state in React applications, data modeling and processing, and caching and memoization.
