Using common web technologies like HTML5, CSS3, and JavaScript, developers may create cross-platform mobile applications with the help of the flexible open-source PhoneGap framework. PhoneGap streamlines the process by allowing developers to create a single codebase that functions flawlessly across several operating platforms, including Windows, iOS, and Android, rather than creating platform-specific code. The framework gives the app a native experience while utilizing web capabilities, which makes it a practical choice for companies looking to expand their customer base with little development labor.
