Key changes include `strict: true` becoming the default, removal of deprecated flags like `out` and `suppressImplicitAnyIndexErrors`, and updated module/target inference logic. The guide provides a step-by-step migration process: auditing current config with `tsc --showConfig`, removing deprecated options, choosing a strict mode strategy (full adoption, incremental opt-in, or selective overrides), and updating module settings explicitly. Complete tsconfig examples are provided for React+Vite, Node.js API, and monorepo setups, along with a reusable migration checklist and troubleshooting tips. Note: TypeScript 6.0 is unreleased; all claims should be verified against official release notes. ## Full article daily.dev links to this article rather than hosting it.
