I need to implement a functionality to skip or ignore the subscription on the fromEvent() observable when a specific condition is met: if
this.currentPosition === this.vc.getScrollPosition()[1]fromEvent(window, 'scroll').pipe(
distinctUntilChanged(),
debounceTime(1000)
)
.subscribe(
(event) => {
const current = this.positions.find(e => e.name === this.currentSectionName);
const indexOfCurrent = this.positions.indexOf(current);
if (indexOfCurrent + 1 === this.positions.length) {
// remain in the same position if it's the last item
this.vc.scrollToPosition([0, current.position]);
this.currentPosition = current.position;
} else {
// move to the next position if it's not the last item
const next = this.positions[indexOfCurrent + 1];
this.vc.scrollToPosition([0, next.position]);
this.currentPosition = next.position;
}
}
);
