React Native and Expo: The Dynamic Duo of Mobile Development
1 ) Introduction to React Native
React Native is a cutting edge JavaScript library that enables developers to create truly native mobile applications for Android, iOS, and other platforms using React. It combines React’s programming paradigm with native platform UI components, ensuring apps have the look and performance of native apps, not compromised user experience.
2 ) Core Features of React Native
React Native uses native platform APIs by rendering components like View, Text, and Image to native UI building blocks.
It separates JavaScript from UI rendering by running JavaScript code on a different thread, which enhances performance, especially for animations.
Developers write declarative UI using React’s composability and state driven rendering, minimizing manual UI updates.
3 ) Why Use a Framework with React Native?
Although React Native can be used alone, most developers benefit from using a framework like Expo. Frameworks provide:
Built in essential APIs for navigation, native module access, and file based routing, reducing boilerplate and complexity.
A developer ecosystem and community driven libraries that simplify app creation and maintenance.
Tools to handle native changes effectively without managing native code files manually.
4 ) Expo: The Recommended React Native Framework
Expo is a production grade framework that significantly boosts React Native development by offering:
Developer tooling such as Expo Go for quick testing and expo dev client for custom native modules.
High quality universal native libraries with over 50 modules ready for use.
File based routing to create stack, modal, drawer, and tab screens simply via the filesystem.
An active, open source community and close collaboration with the React Native team at Meta for cutting edge features.
Additional services like Expo Application Services (EAS) to support app development lifecycle needs.
5 ) Community and Ecosystem
React Native was released by Meta (formerly Facebook) in 2015 and has grown to be a vibrant thanks to widespread contributions from individuals and companies such as Microsoft and Callstack.
The community actively supports various platforms beyond mobile, including React Native Web, Windows, and macOS.
Thousands of apps worldwide use React Native, highlighting its robust adoption and viability.
6 ) Developer Advantages
React Native lets web developers leverage their existing React skills to develop native mobile apps, accelerating development speed and reducing learning curve.
It promotes code reuse and parity across native platforms, making maintenance easier and more efficient.
Expo enhances developer productivity through tooling, pre built modules, and seamless integration with native capabilities.
7 ) Getting Started
Developers can start building apps with React Native via Expo by running simple commands like `npx create expo app@latest`.
Comprehensive guides and documentation support both newcomers and experienced developers to create production ready applications quickly.
Conclusion
Combining React Native’s native first approach with Expo’s powerful development framework creates a powerful ecosystem that democratizes mobile app development. This dynamic duo offers a streamlined, high performance, and developer friendly environment for building beautiful native applications efficiently across multiple platforms.

In 2025, top Angular libraries offer modern, feature-rich components and tools for building dynamic web apps. From powerful data grids to low-code platforms like UI Bakery, these libraries enhance development speed, UI design, and scalability, making them essential for Angular developers.
Migrating from AngularJS to Angular 17 involves gradually upgrading your app by running both frameworks together using tools like ngUpgrade, rewriting components in TypeScript, and adopting Angular’s modern architecture to enhance performance, maintainability, and long-term support.
Angular state management tools help organize and handle app data efficiently, improving scalability and maintainability. Popular options include NgRx for robust, RxJS-based patterns, and newer Signal Store solutions that offer simpler, reactive approaches integrated tightly with Angular’s latest features.
RxJS in Angular empowers developers to manage asynchronous data streams with powerful operators like `forkJoin`, `combineLatest`, and `zip`. Mastering these key operators in 2025 is essential for building efficient, reactive applications that handle complex event sequences seamlessly.
Angular performance optimization in 2025 focuses on improving app speed and responsiveness by using techniques like OnPush change detection, lazy loading, efficient data caching, and AOT compilation. These practices reduce load times, enhance user experience, and ensure scalable, fast Angular applications.
In 2025, Angular remains preferred for large-scale, enterprise apps with its robust, all-in-one framework, while Vue attracts developers seeking simplicity and fast development for smaller projects. Both frameworks excel, with choice driven by project needs and team expertise.
Angular Signals are a new reactive primitive in Angular 16 that enable fine-grained, efficient change detection by automatically tracking dependencies and updating only affected parts of the UI. They simplify state management and boost app performance, revolutionizing Angular's reactivity model.
Angular interview questions to prepare in 2025 focus on core concepts like components, directives, data binding, routing, and dependency injection, along with TypeScript mastery and latest Angular features to ensure strong practical knowledge for building scalable, efficient web applications.
AngularJS reached its official end of support in January 2022, meaning no further updates or security patches. To ensure app security and performance, developers should consider migrating to modern Angular versions or seek third-party long-term support options if immediate migration isn’t possible.
The Angular Roadmap 2025 highlights upcoming features focused on improving developer experience and performance, including zoneless Angular, Signals integration, enhanced Forms, async data handling, improved HMR, and expanded Angular Material/CDK enhancements, driving modern, efficient web app development.
