Hi everyone!
This week we have an exciting sneak peek of the future of React and memoization, and a lot of Lee Robinson's related content 😄
Expo is going strong in the React-Native ecosystem and the app stores 💪
JavaScript Rising Stars 2023 has been published. This year I had the opportunity to comment on the React section. shadcn/ui and Bun took the world by storm. I’m also thankful for Theo recommending my newsletter in his related trend analysis video: welcome to all of you who signed up recently 🙏
Paris 2024 is not only the Olympic Games: we are also back at the center of the React conf world!
Since the end of React Europe, there has been a lack of great React conferences in Paris. It’s finally fixed with 3 great upcoming confs 👌
📅 22 March - React Paris - The crew behind React Brussels and BeJS is launching a new conference in Paris and a great line-up has just been announced today!
📅 22-23 April - React Connection + React-Native Connection - Last year’s half-day React-Native conference that I helped organize was a great success. So it returns this year as a 1-day + 1-day conference, making it more worth it to travel. CFP is open until 3 February.
I’ll try to attend both, and hope to meet some of you there!

The future of React.use and React.useMemo - a powerful alternative to context selectors
Colin explains how React context can cause performance problems, the lack of a context selector API, and how he optimized an app’s performances thanks to the userland use-context-selector implementation from Daishi Kato.
The most interesting part is a great summary of the recent Twitter discussions. Dan Abramov explained context selectors do not compos well. Andrew Clark shared the plan to extend useMemo() and allow the usage of other hooks inside it. This would work with the use hook with any Usable types (currently context and promises, but maybe Observables and stores in the future?), but also third-party hooks! This would solve the fine-grained selection problem in a performant and composable way, and be compatible with the upcoming React Forget compiler.
Great writeup from Dan Abramov, giving good reasons for code to run locally (instant feedback), as well as remotely (close to the data source). He proposes a new React formula: UI = f(data, state), where f represents all your whole React app, running in 2 distinct environments.
This ends with a great question, implicitly asking if you would invent React Server Components to solve this problem.
Is there some way we could split components between your computer and mine in a way that preserves what’s great about React? Could we combine and nest components from two different environments? How would that work?

📱 React-Native
Evan Bacon gathered an impressive list of 1,599 apps that are using Expo libraries (and therefore, React Native). The list includes household names like Pizza Hut, Burger King, Microsoft, Discord, Shopify, NFL, Walgreens, Amazon, CNN, and many more. It’s not news to us that React Native is thriving, but it’s nevertheless encouraging to see the big role that it plays when you look at top apps in the App Store.
