In this tutorial, we'll look at immutability of primitives, arrays, and objects with JavaScript examples And I'll explain why immutability is important for programming You can also watch the associated video here:
- Four Ways to Immutability in JavaScript - DEV Community
For those, we have several built-in methods Spread Syntax As of ES2015, the spread operator has allowed for expanding iterable values into explicit arguments When used inside new array or object literals, this permits copying the properties of existing values into the new value:
- How to Preserve Immutability of Objects in JavaScript - GeeksforGeeks
In JavaScript, we can preserve the immutability of objects using these methods: JavaScript Object freeze () method is used to freeze an object Freezing an object does not allow new properties to be added to the object and prevents removing or altering the existing properties
- Achieving Immutability in JavaScript and TypeScript
In this post, we’ll explore several methods to achieve immutability, including Object assign (), the spread operator ( ), and structuredClone () We’ll dive into how these methods work, highlighting shallow vs deep cloning and providing code snippets for clarity Why Immutability?
- JavaScript Immutability – Frozen Objects in JS Explained with Examples
Object immutability is supported in JavaScript through a simple API – Object freeze(): name: ‘John‘ Once an object is frozen, you cannot: The freeze operation shallowly traverses owned, enumerable properties and seals them to prevent future mutation Let‘s walk through some examples 1 Simple Object Freeze name: ‘John‘
- Immutability in JavaScript: Why It’s Important and How to . . . - codedamn
How to achieve immutability in JavaScript? You can achieve immutability in JavaScript using the Object freeze() method, the const keyword, or using libraries like Immutable js, Immer, and Mori For further understanding, you can refer to the MDN documentation on Object freeze () and the library documentation for Immutable js, Immer, and Mori
- How to Make Your JavaScript Code Immutable
The short and simple answer is: yes, it is possible to protect an object from modification The JavaScript standard provides the Object freeze method for such cases You pass the object you want to protect to it and afterwards no more changes are possible
- Why is Immutability so Important in JavaScript? - GeeksforGeeks
Importance of Immutability in JavaScript What is the good part of the immutability? Why do we need to care about the immutability in the first place? Why even bother? Immutability gives stricter control over your data immediately making your code safer and more predictable
