Deep relative imports are a maintainability tax. Once a project grows, ../../../ becomes noise and refactors get painful. I define a small set of path aliases (like @/* for app code) and keep them consistent across TypeScript, Jest/Vitest, and the bun

I want linting to catch bugs, not fuel style debates. I use ESLint for correctness rules (unused vars, no-floating-promises, React hooks rules) and let Prettier handle formatting. I keep overrides minimal and justified. I also treat lint as part of CI

Formatting consistency matters, but humans shouldn’t be the ones enforcing it in code review. Prettier makes diffs smaller and reviews more focused on logic. I keep the config minimal and aligned with team expectations (singleQuote, trailing commas, ~
