Summary: Pull Request resolved: facebook#56772 Upgrades to TypeScript 6.0.3 and updates `typescript-eslint/*` for TS 6.0 compatibility across `react-native` and `metro`. #### Motivation TypeScript 6.0 (Mar 2026) will resolve facebook#53565. Before updating in the React Native CLI template, align in RN and Metro source for consistency. This is an internal change since: - This upgrade only applies to TS analysis of these repos' source code. - Edits to `react-native/typescript-config/tsconfig.json` (which *is* distributed) maintain backwards compatibility. #### Changes **react-native** - Bump `typescript` from `^5.8.3` to `^6.0.3` - Bump `typescript-eslint/*` from `^8.24.0` to `^8.59.2` - Replace deprecated `moduleResolution: "node"` with `"node16"` and `target: "es5"` with `"es2015"` in codegen-typescript-test - Add explicit `types: ["jest", "node"]` where needed (TS 6.0 defaults `types` to `[]`) - Set `strict: false` in configs that only enable specific strict flags (TS 6.0 defaults `strict` to `true`) - Update `ModuleResolutionKind.NodeJs` to `Node16` in build config **metro** - Bump `typescript` from `5.8.3` to `^6.0.3` - Bump `typescript-eslint/*` from `^8.36.0` to `^8.59.2` - No tsconfig changes needed (`tsconfig/node20` preset is already TS 6.0 compatible) Changelog: [Internal] Differential Revision: D104658690
