i have 2 event streams: let mousedowns = rx.observable.fromevent(document.body, "mousedown"); let mouseups = rx.observable.fromevent(document.body, "mouseup"); i subscribe mouseups preceeded mousedown. normally remember state so: let isdown = false; mousedowns.subscribe(() => down = true); mouseups.filter(() => isdown).subscribe(() => console.log("captured"); this feels rather un-"reactive"... elegant way same thing? it depends on if want stop listening mouse ups until next mouse down. mean, if goal have observable tells if mouse down, you'd like: const ismousedown = rx.observable .merge( mousedowns.map(() => true), mouseups.map(() => false)) .startwith(false); ismousedown.subscribe(state => console.log("is mouse down? " + state)); if want trigger after down/up sequence you'd do: const myclicks = mousedowns.switchlatest(() => mouseups); myclicks.subscrib...

i need handle case when desired ssid connected or configured in list, meanwhile if security changes, how should notified currently, getting supplicant state "disconnected" when desired network connected , meanwhile if security changes. i didn't understood needs. how different check networkstate ? official docs supplicantstate states: these enumeration values used indicate current wpa_supplicant state. more fine-grained users interested in. in general, better use networkinfo.state . so how different check network state change in app ?
