React Native, the popular open-source framework for building mobile applications, has recently released version 0.72. This new iteration brings several exciting changes and improvements that are worth exploring. In this article, we'll delve into the key updates in React Native 0.72 and discuss why they matter to developers and the broader mobile app development community.

TurboModules: A Game-Changer for Performance

One of the standout features in React Native 0.72 is the introduction of TurboModules. TurboModules is an architectural change that aims to significantly boost the performance of React Native apps. This update replaces the older Native Modules infrastructure with a more efficient and streamlined system. It promises improved startup times and runtime performance, which is crucial for delivering a smoother user experience.

TurboModules make it easier for developers to create and maintain native modules, reducing the complexity of the development process. This architectural change is a significant step forward in enhancing the performance of React Native applications and making them more competitive with fully native apps.

Lean Core: Streamlining the Framework

React Native 0.72 has embarked on a mission to slim down its core library. This initiative, known as Lean Core, aims to remove less-used or deprecated modules from the React Native framework. This not only reduces the framework's size but also makes it easier for React Native app development companies to maintain and upgrade their apps.

By decluttering the core library, React Native becomes more modular, allowing React Native developers to add only the components they need, resulting in smaller app sizes and improved performance. Lean Core is a step towards making React Native a more efficient and future-proof framework.

Hermes 0.8.4: JavaScript Engine Upgrades

React Native 0.72 comes bundled with Hermes 0.8.4, an update to the JavaScript engine used in React Native. Hermes is renowned for its ability to optimize JavaScript code for better execution speed and smaller app sizes. With this upgrade, developers can expect improved JavaScript performance and reduced memory consumption, resulting in more responsive and efficient apps.

Improved Reliability and Compatibility

The React Native community has focused on improving the reliability and compatibility of the framework in version 0.72. Several bug fixes and enhancements have been made to ensure a smoother development experience. These changes not only benefit existing projects but also make it easier for React Native app development companies to upgrade to the latest version without facing compatibility issues.

Enhanced Accessibility Features

Accessibility is a critical aspect of app development, and React Native 0.72 has introduced several enhancements to make it easier for developers to create inclusive and accessible mobile applications. These improvements include better support for voice-over on iOS and TalkBack on Android, making it more straightforward for developers to ensure their apps are accessible to a broader audience.

Community-Driven Development

React Native 0.72's development has been heavily influenced by the React Native community. The framework's open-source nature means that developers from around the world contribute to its development. The discussions on platforms like GitHub and blog posts demonstrate the collective effort to make React Native a better framework.

In conclusion, React Native 0.72 introduces a host of improvements and changes that make it an exciting update for developers. The introduction of TurboModules, the Lean Core initiative, upgraded JavaScript engines, enhanced reliability, and improved accessibility features all contribute to a more efficient and user-friendly framework.

React Native app development companies should consider upgrading to leverage these improvements and enhance their mobile app development projects. If you are looking to Hire React Native developers, the latest version of React Native offers exciting opportunities for your projects. Whether you are a software company in Vietnam or from anywhere around the world, React Native 0.72 has something significant to offer in the realm of React Native app development.
