Frequently Asked Questions

Metizsoft optimizes website performance using code-splitting, lazy loading, caching, and efficient data structures to reduce server requests. We conduct multiple performance tests at various development stages and provide architecture recommendations for seamless scalability. For JavaScript performance best practices, refer to MDN Web Docs at developer.mozilla.org/en-US/docs/Web/Performance.
JavaScript development costs depend on the project scope, complexity, and technology stack. A simple SPA or landing page starts from $8K-$25K. A mid-complexity web application with API integrations, authentication, and a backend typically runs $25K-$80K. Enterprise JavaScript platforms with microservices, real-time features, complex state management, and cloud infrastructure can range from $80K-$300K+. We provide transparent, milestone-based estimates after a free scoping session.
We implement comprehensive security best practices across all JavaScript projects: Content Security Policy (CSP) headers, HTTPS enforcement, JWT-based authentication with secure token rotation, XSS prevention through input sanitization and output encoding, CSRF protection, dependency vulnerability scanning (npm audit, Snyk), OWASP Top 10 compliance reviews, rate limiting, and secure API design with proper authorization at every endpoint. Security is built into our development process not added at the end.
Our JavaScript development team follows a continuous learning culture dedicated R&D time each week for framework updates, internal knowledge-sharing sessions, attendance at JavaScript conferences (React Summit, VueConf, Node Congress), contributions to open-source projects, and mandatory reading of official release notes for all major frameworks we use. We maintain a curated tech radar that tracks emerging tools and patterns, ensuring every recommendation we make is based on current best practices.
Our JavaScript maintenance service covers: dependency updates (keeping npm packages current and free of known vulnerabilities), browser compatibility testing with each major browser release, performance monitoring and Core Web Vitals optimization, Node.js version upgrades, bug fixes and crash resolution, feature additions, and infrastructure scaling. We provide 24x7 monitoring with automated alerting and SLA-backed response times for production-critical JavaScript applications.
