Google I/O Extended 2024 is an event organized by local developer communities, universities, or tech organizations worldwide. It serves as an extension of Google's main developer conference, Google I/O, bringing together developers, enthusiasts, and industry professionals who couldn't attend the main event in person. Attendees typically watch live streams or recordings of keynotes, sessions, and workshops from Google I/O while also participating in local activities like hackathons, code labs, and networking events. It's a great way for developers to connect, learn, and engage with the latest developments in Google's technology ecosystem within their own communities.
