Slow web apps lose users. Lazy loading and code splitting fix this. You send users only the code they need. This makes your site load faster.

Use these strategies to improve speed:

• Route-based splitting: Load code for the page the user visits.
• Component lazy loading: Load heavy parts only when they appear on screen.
• Image lazy loading: Use the loading="lazy" attribute for images below the fold.
• Font optimization: Use font-display: swap to stop invisible text.

Measure your results. Use Lighthouse to track Largest Contentful Paint and Time to Interactive. Aim for under 200KB of JavaScript for the initial load.

Follow these rules for better apps:

• Put user experience before developer ease.
• Keep state management simple. Use local state for most things.
• Use TypeScript to find bugs early.
• Build for accessibility from the start.

Try this plan:

• This week: Run a performance audit.
• This month: Fix accessibility issues.
• This quarter: Build a design system.
