Frequently Asked Questions

Which web development framework will be most popular in 2025?

In 2025, modern frameworks like React, Vue.js, and Angular will maintain their popularity. React 19's new features (Server Components, React Compiler) will increase performance and development speed. Vue.js 3.5's Composition API and Angular 18's standalone components also offer significant advantages for developers. You should choose a framework based on your project's needs.

How is AI used in web development?

AI is used in web development for code writing, test automation, debugging, and performance optimization. Tools like GitHub Copilot and ChatGPT assist developers. AI automates repetitive tasks, reducing development time and improving code quality. AI integration will become even more widespread in 2025.

When should serverless architecture be used?

Serverless architecture is ideal for projects requiring scalability, traffic fluctuations, and reduced maintenance costs. It's perfect for APIs, microservices, data processing, and event-driven applications. However, it's not suitable for long-running processes and applications requiring high memory.

What is Progressive Web App (PWA) and why is it important?

PWA is a technology that enables web applications to provide a mobile app-like experience. It offers features like offline operation, push notifications, home screen installation, and fast loading. It improves user experience, reduces mobile app development costs, and provides SEO advantages. PWA usage will continue to grow in 2025.

What security measures should be taken for web security?

For web security, HTTPS usage, strong authentication (2FA), regular security updates, input validation, SQL injection and XSS protection, rate limiting, and security scans should be implemented. Following OWASP Top 10 security vulnerabilities and conducting regular security audits are critical.

How can I optimize web performance?

To optimize web performance, implement image lazy loading, code splitting, CSS/JS minification, CDN usage, caching strategies, critical CSS inline, JavaScript defer/async usage, and bundle size optimization. Tracking Core Web Vitals metrics (LCP, FID, CLS) and using PageSpeed Insights is important.
