RXJS custom withLatestFrom

// Comment for https://stackoverflow.com/a/75048174/8234174
const source = new Subject();
const one = new Subject();
const two = new Subject();

source.pipe(awaitLatestFrom([one, two])).subscribe(data => console.log('Entered with data:', data));

source.next('A');
one.next("One")
source.next('B');
two.next("Two")
// Will not log "Entered with data", as 'one' has not fired again since 'source' has nexted value 'B'
