Forever Functional: Immutable objects for safer state

• seamless-immutable

  1 5,367 0.0 JavaScript

  Immutable data structures for JavaScript which are backwards-compatible with normal JS Arrays and Objects.

Here we'll study the varied ways that JavaScript provides, such as object freezing and cloning, so we can get a basic understanding of what a full immutability solution needs. We won't try, however, to achieve 100% production-ready code, possibly dealing with getters, setters, private attributes, and more; for this I would rather suggest looking at available libraries such as Immutable, Immer, Seamless-immutable, and others.

  A JS library for predictable global state management

  

It's impossible to enforce a rule that will make developers work in safe, guarded ways. However, if we can manage to make our data structures immutable (and we'll keep state in such an object) we'll control how the state is modified. We'll have to work with some interface that won't let us directly modify the original data, but rather produce a new object instead. (Observant readers may notice that this is exactly the idea behind Redux: you don't directly modify state: you have to dispatch an action, which a reducer will process to produce a new state.)

• SurveyJS
