Imutability, react and typescrip: how to do it the clean way?
Check out Object.freeze. There's also Immutable.js for working with immutable data.

How To Scale Your React Applications
Use immutability to manage state updates When updating state in your React application, it's important to ensure that you are not mutating the original state object. Instead, you should create a new copy of the state object with the updated values. Immutability makes it easier to manage state updates and ensures that the updates are performed in a predictable and safe manner. Libraries like Immutable.js provide a set of functions that simplify working with immutable data in React applications.

Is it possible to strongly type properties of class dynamically added in the constructor?
We're wanting to get rid of immutable so I'm trying to replicate what it is about the Record functionality and types that allow this dynamic property access to work. After pulling my hair out looking through the [email protected] type definitions and the actual code, to me it looks like the types are just kind of lying about what's going on ... and it's just working. Does anyone have any ideas how I can replicate this dynamic property access with strong typings?

Functional immutable game state
The Immutable.js README has a much more complete description of immutability and why you might want to use the library. Also worth mentioning that Immer is an alternative which is a bit easier to get started with.

Immutable Collections should be Your Default
I can't speak to C# and Java, but the suggestion in this post: ImmutableJS already uses Persistent data structures. (It's the second sentence of their introduction)

How do I type reduce when Im reducing an array to count elements?
Avoiding mutation is just never modifiyng an object, ever. There are tons of implementations of this pattern, notably immutable.js (https://immutable-js.com/), Redux is also an example of this philosophy.

Alan Perlis and the Evolution of Programming Languages
JavaScript is most programers' first introduction to map, filter, and reduce. Easy lambdas made those higher-order functions a staple of a lot of JS code.
Meanwhile, immutable.js[0] is at 10 million downloads per week and rising.
I would add that it's not just the ease of use of lambdas, but the fact that in JavaScript functions really are first class citizens. Most of the other widely used languages that people start on have lambda functions added in as a bit of a hack and only treat some functions as real values.

Testing Defer Blocks in Angular with Cypress
Recently I came across this issue while triaging some issues at Cypress. (Shout out to MattiaMalandrone for creating an issue with clear instructions for how to reproduce). After quickly replicating the issue I sought after a solution which ultimately inspired me to write this article.
- Cypress changed older versions to block third-party plugins (ignoring lockfiles)
- Cypress can't open Tesla.com website

/Does Cypress Component Testing Work With Libraries
This questions was asked a while ago and pretty much went unanswered: https://github.com/cypress-io/cypress/issues/23677. If it doesn't work with libraries yet I will stop battling with it for now. If it doesn't work, what are you using to test libraries?
