Dead Code kills silently

Short summary

Dead code silently bloats JavaScript bundles and slows Time to Interactive. Detect unused code with TypeScript compiler flags, knip (for project-wide analysis), and ESLint. Enable tree-shaking in Vite/Rollup and mark sideEffects: false in package.json to automatically eliminate dead code at build time.

• •Unused JavaScript accumulates across releases, inflating bundle sizes and slowing load times
• •Use TypeScript, knip, and ESLint to catch dead code before it reaches production
• •Configure tree-shaking and sideEffects to automatically remove unused code at build time
