1. Front-End Foundations
   Why does my CSS flexbox layout break on older browsers? Modern browsers handle flexbox well today, but older versions—like Internet Explorer 11—require vendor prefixes such as -webkit- or -ms- to ensure compatibility. Using tools like Autoprefixer in preprocessing pipelines resolves most cross-browser inconsistencies efficiently.
2. Back-End Dynamics
   When should I use REST over GraphQL in API design? REST suits simple CRUD operations with predictable endpoints; GraphQL excels in scenarios requiring flexible data queries across multiple resources, reducing over-fetching and simplifying client-server interactions.
3. Security Best Practices
   How do I prevent Cross-Site Scripting (XSS) attacks? Always sanitize user inputs using server-side validation libraries like DOMPurify or built-in frameworks such as React’s built-in escaping mechanisms to neutralize malicious scripts before rendering.
4. Performance Tuning
   What are key techniques to optimize page load speed? Leveraging browser caching via service workers, minimizing HTTP requests through asset bundling, and lazy-loading images reduce latency significantly—directly improving user retention and SEO rankings.
5. Developer Workflow
   Why integrate version control like Git early in development? It enables collaborative coding with branching strategies, rollback capabilities during bugs, and transparent change tracking—critical for maintaining code integrity in team environments.
