JavaScript Development FAQs

Common questions about JavaScript services

Both are excellent choices. React has a larger ecosystem and is ideal for complex applications. Vue.js has a gentler learning curve and works great for progressive enhancement. We'll help you choose based on your team's skills, project requirements, and long-term goals.

TypeScript adds static typing to JavaScript, catching errors during development instead of runtime. It improves code quality, enables better IDE support, and makes large codebases more maintainable. It's especially valuable for enterprise applications and large teams.

Absolutely! Node.js excels at handling concurrent requests thanks to its non-blocking, event-driven architecture. Companies like Netflix, LinkedIn, and Uber use Node.js for high-traffic applications. Proper architecture, caching, and scaling strategies ensure excellent performance.

Next.js adds server-side rendering, static site generation, automatic code splitting, and optimized performance out of the box. It's excellent for SEO, provides faster initial page loads, and includes built-in routing and API routes. Perfect for production-ready applications.

We use ESLint for code linting, Prettier for formatting, comprehensive testing (Jest, Cypress), code reviews, TypeScript for type safety, and follow established patterns like SOLID principles. Our CI/CD pipeline ensures code quality before deployment.
