* Add CityJS New Delhi 2026 conference details * Update CityJS New Delhi date to 2025
The previous sentence "If you are using React Compiler, useMemo, useCallback, and React.memo can be removed." was coming off a bit too strong and makes it incorrectly seem like the manual memos and compiler memos are 1:1. Removing the sentence doesn't take anything away from this paragraph, so let's remove it to reduce confusion.
Updates our previous RC blogpost to point people to the `rc` tag, not the specific rc version
The compiler rule is now enabled by default in 6.0.0-rc.2, so there is no longer a need to manually enable the compiler rule in user's eslint configs.

Fix "documentatino" typo to "documentation" in comment about useOptimistic reference page.

The previous examples used a service called loremflickr.com to link to placeholder images. Since that service is now down, I updated them to reference placecats.com instead, which we already use in other examples as well. placecats doesn't have the same random cat feature so I roughly approximated it in the example code. Closes #7966
* Fix handleClick compiler intro example * Use a note instead * Update src/content/learn/react-compiler/introduction.md
* fix: changed source file names in docs from App.js, index.js and styles.css to src/ dir * fix: updated wrong image with the correct one with current sandbox file structure * refactor: reverted all formatting and just just mention src folder in introductory section * Reverted changes tutorial-tic-tac-toe.md * added enhanced image of sandbox
Previously, `createFileMap` split the MDX meta string on spaces and assumed the first token was the filename. Once we prefixed code fences with `{expectedErrors: ...}`, it would incorrectly parse the meta and crash.
This PR updates createFileMap to skip tokens in the meta containing a start and end brace pair (using a stack to ensure we close on the correct brace) while tokenizing the meta string as expected.
Test plan: pages reported in #7994 no longer crash on the next PR
Closes #7994
* Ignore braces when building Sandpack file map

For local dev and CI we want to have the eslint-local-rules running, so let's make sure both have their dependencies installed. We don't use a monorepo setup here, which is why they're currently setup as a two completely independent yarn workspaces.
Adds new docs for our new eslint rules.

We're updating eslint-plugin-react-hooks with support for useEffectEvent usage and updated configuration options for applying the useEffectEvent and other effect rules to custom effect hooks. This adds the documentation for the config syntax and adds mention to the useEffectEvent reference page that the linter should be used to ensure proper usage of Effect Events.
