What is a Cross-Platform App Development Framework?
A cross-platform app development framework allows developers to create applications that can run on multiple operating systems from a single codebase. Instead of writing different codes for iOS, Android, and other platforms, developers can use these frameworks to write code once and deploy it across various platforms. This approach saves time and resources, enabling faster development and easier maintenance. Cross-platform frameworks typically use languages like JavaScript, Dart, or C#, and they provide tools and libraries to bridge the gap between different operating systems. The key advantage is the ability to deliver a consistent user experience across multiple devices, ensuring broader reach and uniform functionality.
