What is WebTransport and can it replace WebSockets?

WebTransport is a new specification that could offer an alternative to WebSockets for applications requiring low-latency, event-driven communication between endpoints. Unlike WebSockets, which creates a single stream per connection, WebTransport allows multiple streams over a single connection and works with HTTP/3, the upcoming version of the transport protocol used by the World Wide Web. It uses both reliable and unreliable data transfer methods, making it suitable for various use cases such as bidirectional data streaming for multiplayer gaming, interactive live streams, and data transfer for sensors and internet of things devices.
