I'm enjoying playing Activity x Jotai now in React 👻
Can you confirm what is happening here?

The refresh logic can be implemented as an interval instead.

ECMAScript excitement 😉

TypeScript's @chronicles.org is pitching enum in JS 🎉

It's the good parts of TS enum + enhancements:

🔶 More datatypes: Symbols etc
🔶 Iterable
🔶 Immutable
🔶 Null prototype
🔶 No declaration merging
🔶 Compatible with Node type-stripping 👍

In RSCs, we should be careful when passing multiple promises to client components.
In <PatternA />, all components are displayed after 10 seconds under a single <Suspense />.
In <PatternB />, <User /> appears first after 5 seconds, then <NewsB /> is shown.

ドーナッツが"use client"を制する鍵?

Premise: App Router in Next.js.

This page has tabs and buttons. Because of that, these elements need to be client components, so 'use client' is required.
How would you design your component tree? If you follow the “donut” mindset, the answer should become clear on its own.

Today, we’re deprecating Create React App for new apps, and encouraging existing apps to migrate to a framework.

We’re also providing docs for when a framework isn’t a good fit for your project, or you prefer to start by building a framework.
