I'm trying to tighten up my TypeScript codebase and would love some community wisdom. What overall approach do you follow for typing complex data structures without over-engineering? How do you balance strictness vs. flexibility in a large project? Any recommendations on organizing types, using utility types, and setting up linting rules that keep the code readable? Also, how do you handle migration from plain JavaScript to TS in an existing codebase? Looking for practical steps rather than tool-specific tricks. What has worked best for you?

In my last project, I first enabled `strict: true` in tsconfig and created interfaces for the main objects, using the `Pick` and `Partial` utilities to avoid duplicating complex types. For the migration, I renamed the .js files to .ts one by one, temporarily added `// @ts-ignore`, and then resolved the errors with ESLint + @typescript-eslint to keep the code readable.
