get sname: ƒ reactiveGetter()
set sname: ƒ reactiveSetter(newVal)
get stheme: ƒ reactiveGetter()
set stheme: ƒ reactiveSetter(newVal)
get scolor: ƒ reactiveGetter()
set scolor: ƒ reactiveSetter(newVal)
get stcount: ƒ reactiveGetter()
set stcount: ƒ reactiveSetter(newVal)

set sid: ƒ reactiveSetter(newVal)
__proto__: Object
1: {…}
2: {…}
3: {…}
4: {…}
