Tom Spencer ae67c5ac45 Disable ESLint `no-undef` for TypeScript files (#32655 ) Summary: The `typescript-eslint` project [recommends that `no-undef` is disabled for TypeScript files](`6c3816b383/docs/linting/TROUBLESHOOTING.md (i-get-errors-from-the-no-undef-rule-about-global-variables-not-being-defined-even-though-there-are-no-typescript-errors)`), since TypeScript itself will perform this check. Disabling this config property has two benefits: - Undefined variables and types will only be reported once, by the TypeScript compiler. Currently they are reported twice: once by TypeScript, and once by ESLint: <img width="506" alt="Screenshot 2021-11-24 at 12 38 22" src="https://user-images.githubusercontent.com/820863/143239961-eb8ed709-60f9-490a-bda3-fc581673d56c.png"> - Types that are declared globally by React Native will no longer be erroneously reported as undefined - this is currently the case for some types, e.g. `Blob`: <img width="419" alt="Screenshot 2021-11-24 at 12 40 04" src="https://user-images.githubusercontent.com/820863/143240213-06428b24-09c8-4f95-8e77-7f4fd160eed1.png"> ## Changelog <!-- Help reviewers and the release process by writing your own changelog entry.
