Would GC work if I create many no-longer-used observables?

[gyhyfj]

For example, if I always create new observable on click or scroll by this callback:

const onClick =()=>of(1,2,3).subscribe(console.log)

Could garbage collector work to clean no longer used observable in browser?

Pretty sure once the observable stream is completed, it will be garbaged collected
