This article discusses how to create a Webex clone using the 100ms JavaScript SDK. The process involves installing dependencies, setting up an account on the 100ms dashboard, defining roles and permissions for participants, and coding various components such as Lobby.js, App.js, VideoTile.js, ConferenceRoom.js, and ControlSection.js to handle user authentication, video conferencing, screen sharing, and meeting controls. The final result is a functional Webex-like application that enables real-time audio-video interactions between participants.
