Example​

Sharing the same Observable​

const subscribe = pipe$$(interval(1000), [
  scan$$$<void, number>(count => (count + 1), 0),
  shareRL$$$<number>(),
]);

subscribe((value: number) => {
  console.log('value - A:', value);
});

// note that interval(1000) is only subscribed once
subscribe((value: number) => {
  console.log('value - B:', value);
});

Output:

// 1000ms
value - A: 0
value - B: 0
// 1000ms
value - A: 1
value - B: 1
