Anyone starting a tech startup will face this decision: Should I start with a database that has built-in support for sharding? Or should I just start with MySQL or PostgreSQL and defer the sharding question for later? Notion chose to do man

Deny, deny, deny. Which you'd expect him to do. Of course we don't put profits above safety and well-being. Of course we don't push content that makes people angry... and so on. But embedded in the denial is a threat to stop

I can agree with most of what you are saying. My alarm stems from the fact that a lot of developers' understanding of FP these days comes from their React experience (which they mistakenly believe is FP) and a lot of these developers

I think you have to start by answering this question: What is the benefit of being functional? If there is no benefit then this whole discussion is moot. If there is a benefit to FP that isn't easily achievable using other styles, then

I am assuming you're debating in good faith (and not just trying to win an argument). The recommendation made in the docs is very well justified. All other techniques are a mess, and lead to maintenance problems and bugs. Just replace

Functional Programming has to serve a purpose. What is the point of functional programming? There are 3 benefits, mainly: (1) Ease of verification, (2) Parallelism and (3) Data-centric computation. (See article I linked for details.) Of the

Disagree. Functional programmers often speak of implementing programs with a pure core and a thin layer on the outside that handles effects. (Read the article I pointed to earlier.) If you don't have a pure core then you are not using

You didn't read the article. How to deal with impurity is described in the article.

Functional Programming is about purity. At the core of FP is pure functions. If you don't care about purity don't use FP. There is a lot to like about React, and Hooks and so on. Just don't call it FP though.

Once you realize React doesn't work for complex components it loses its attraction. Web Components are conceptually way simpler and work well. See example: https://github.com/wisercoder/uibuilder/blob/mas

That works well... until you have stateful components and you want to send in new props. At that point the recommended approach is to replace the entire component by using the key property. For simple components, especially stateless ones,
