Frequently Asked Questions

We built strategies before development that work just for you.

What is React, and why should I choose it for my web development project?

React is a JavaScript library for building user interfaces, particularly for single-page applications. It’s known for its component-based architecture, which makes UI development more modular and efficient. Choosing React can lead to faster development, improved code maintainability, and a better user experience.

What are React Hooks, and how do they improve functional components?

React Hooks are functions that allow functional components to use state and lifecycle features previously available only in class components. They enhance the flexibility and reusability of functional components by enabling them to manage state and side effects, making code more concise and readable.

What is JSX, and why is it used in React?

JSX (JavaScript XML) is a syntax extension for JavaScript that allows you to write HTML-like code within your JavaScript files. React uses JSX to describe what the UI should look like, making it more readable and concise compared to using pure JavaScript.

What are the key benefits of server-side rendering (SSR) in React?

Server-side rendering in React involves rendering the initial HTML on the server rather than in the browser. This improves performance, SEO, and the user experience by delivering a fully rendered page directly to the client, reducing the time it takes to load and display content.

How does Zealous approach the development process using React?

Zealous follows an agile development methodology, emphasizing collaboration, adaptability, and transparency. Our process includes thorough planning, design, implementation, testing, and continuous communication to ensure client satisfaction.

What types of applications can Zealous develop using React?

Zealous specializes in developing a wide range of applications, from dynamic single-page applications (SPAs) to complex enterprise-level systems. We excel in crafting solutions for e-commerce platforms, content management systems, and more.

Can Zealous migrate existing applications to React?

Yes, Zealous provides migration services for businesses looking to upgrade their existing applications or transition from other frameworks to React. Our team ensures a smooth transition while maintaining data integrity and minimizing downtime.

What ongoing support and maintenance services does Zealous provide for React applications?

Zealous offers continuous support and maintenance services, including bug fixes, updates, and feature enhancements, to ensure the longevity and optimal performance of React applications even after the initial development phase.
