- We create wireframes or high-fidelity Figma UI designs based on agreed-upon requirements and user journeys.
- We plan responsive layouts, reusable components, interactions, and key states before development starts.
- Designs are shared sprint-wise for iterative review rather than waiting until the entire project is complete.
- Each screen, template, or flow is approved prior to development to avoid rework.
Technology-specific Development
- Build dynamic single-page applications (SPAs) and progressive web apps (PWAs).
- Create highly scalable, real-time server architectures using runtime ecosystems.
- Design secure RESTful and GraphQL APIs for seamless third-party data exchange.
- Optimize rendering, code splitting, lazy loading, responsiveness, and Core Web Vitals throughout development.
- Keep development environments aligned with production to prevent surprises during deployment.
- Implement SEO-friendly, marketing-ready practices on public-facing pages to avoid redevelopment.
Milestone Demo Calls & Feedback
- We schedule a demo call at each milestone to walk you through completed functionality.
- You review the build, validate it against the approved scope, and provide feedback.
- Our team works on agreed updates before moving to the next milestone.
- You maintain continuous visibility into the product throughout the development process.
Final QA, Delivery & Deployment
- Our experienced QA team performs functional, responsive, cross-browser/device, integration, and performance testing.

What Clients Usually Ask Us
Why outsource your JavaScript development?
Outsourcing JavaScript development grants access to specialized expertise, accelerates project delivery, and reduces development costs. It frees your in-house team to focus on core business functions, so you can scale up quickly and efficiently while maintaining high-quality results.
What are the most popular JavaScript frameworks?
There are two types of JavaScript frameworks:
– Front-end: AngularJS, RectJS, VueJS
– Back-end: NodeJS, MeteorJS, ExpressJS
What is JavaScript mainly used for?
JavaScript is a programming language used to develop dynamic online applications and interactive web pages through client-side scripting. When using a cross-platform runtime environment, such as NodeJs, it is possible to write server-side JavaScript code.
Is JavaScript used for front-end development?
JavaScript is used for front-end development to build interactive web apps and web pages with simple or complex functions and designs, and is often used to create user-friendly interfaces. However, JavaScript frameworks like Node.Js are widely used for back-end development as well.
Is JavaScript used only for web development?
JavaScript is a scripting language widely used in web application development. However, it can be used in various applications, including mobile and desktop app development, content management systems (CMS), games, smartwatch apps, and enterprise resource planning (ERP) systems.
What is the difference between cross-platform development and native app development?
Native app development involves building separate applications for each platform using the platform’s default language and tools. For iOS, that means Objective-C or Swift with Xcode. For Android, it means Java or Kotlin with Android Studio. Native apps deliver the highest level of performance and the deepest access to device-specific features, making them ideal for complex, resource-intensive applications.
Cross-platform development uses a single shared codebase that runs across multiple platforms including iOS, Android, and web using frameworks like React Native, Flutter, or Ionic. This approach significantly reduces development time and cost since you write once and deploy everywhere, while still delivering a near-native user experience.
How much does it cost to develop a project in JavaScript?
Overall, the cost of developing a project in JavaScript depends on your project’s size, complexity, type, specifications, and budget. Send your requirements to our business analyst team at sales@wpwebinfotech.com. They will estimate time and cost based on your needs. We also offer an hourly and dedicated cost model.
Do you provide any post-development services for JavaScript projects?
Yes, at WPWeb Infotech, we offer ongoing maintenance and support services. Based on the project’s nature and size, we provide two rounds of corrections within two weeks of project completion to resolve bugs, optimize performance, and address any other issues. After completion of this period, we offer hourly slots for minor development & maintenance.
Additionally, we provide yearly maintenance support contracts on a retainer basis that will cover ongoing, hassle-free support and maintenance of your website.
