In Show Paying, what does count do?

const observables = of(numbers, letters)
// observables: [1-2-3]-[a-b-c]X
// count: 1--2X

[Amechi101]

count counts the number of emissions that observable completes. For example [1-2-3] is completed that's a count of 1. Next up in the stream [a-b-c] is completed that's a count of 2.

There is no count observable though right?
