Why using the `children` prop makes `React.memo()` not work

I've recently ran into a pitfall of [React.memo()][memo] that seems generally overlooked; skimming over the top results in Google just finds it mentioned in passing in a [React issue][regit], but not in the [FAQ] or API [overview][react-api], and not in the articles that set out to explain React.memo() (at least the ones I looked at). The issue is specifically that nesting children defeats memoization, unless the children are just plain text. To give a simplified code example:

const Memoized = React.memo(({ children }) => (<div>{children}</div>));
// Won't ever re-render
<Memoized>bar</Memoized>
// Will re-render every time; the memoization does nothing

So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:

There are, however, a few problems:

These solutions use non-keyword tokens (null, true, false are actually Literals, not Keywords)
One of the solutions isn't quite valid (new super)

React recently introduced an experimental profiler API. This page gives instructions on how to use this API in a production release of your app.

Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

A vision for data interchange in Elm

How do you send information between clients and servers? What format should that information be in? What happens when the server changes the format, but the client has not been updated yet? What happens when the server changes the format, but the database cannot be updated?

These are difficult questions. It is not just about picking a format, but rather picking a format that can evolve as your application evolves.

Literature Review

By now there are many approaches to communicating between client and server. These approaches tend to be known within specific companies and language communities, but the techniques do not cross borders. I will outline JSON, ProtoBuf, and GraphQL here so we can learn from them all.

	You are an expert software architect and project analysis assistant. Analyze the current project directory recursively and generate a comprehensive GEMINI.md file. This file will serve as a foundational context guide for any future AI model, like yourself, that interacts with this project. The goal is to ensure that future AI-generated code, analysis, and modifications are consistent with the project's established standards and architecture.

	+ Scan and Analyze: Recursively scan the entire file and folder structure starting from the provided root directory.
	+ Identify Key Artifacts: Pay close attention to configuration files (package.json, requirements.txt, pom.xml, Dockerfile, .eslintrc, prettierrc, etc.), READMEs, folder hierarchy, documentation files, and source code files.
	+ Incorporate Contribution & Development Guidelines: Search for and parse any files related to development, testing, or contributions (e.g., CONTRIBUTING.md, DEVELOPMENT.md, TESTING.md). The instructions within these guides are critical
