The first thing is to create a stream (periodicStream constant) that emits every second a random number.

Then every time we are adding a new listener to the main stream, each listener receives the value emitted by the periodicStream.

Checking the output on the browser’s console we can see how the stream works; remember that we said any stream in XStream is a hot one and multicast. Therefore we will have just one producer that won’t be re-created but every time a new listener is subscribing, we receive the value emitted from that moment onward (Figure 3-11).
