When modernizing an application that used Flash, which technology is recommended for avoiding browser plugins?

The recommended technology for modernizing an application that used Flash and avoiding browser plugins is HTML5. This is due to HTML5's capability to support multimedia elements such as audio and video natively within the web browser without the need for additional plugins. Flash was once the standard for these capabilities, but it has become obsolete due to security vulnerabilities and lack of support. HTML5 provides a more secure, standardized approach to delivering interactive content, making it a better choice for modern web applications.

In addition to multimedia, HTML5 also includes APIs for features like local storage, geolocation, and offline access, which enhances functionality while ensuring a seamless user experience without reliance on third-party plugins. Consequently, using HTML5 aligns with current web development practices and standards, facilitating easier maintenance and compatibility across various devices and browsers.
