Create a stream and subscribe

// - `Stream.fromInterval(100)` creates a stream that emits a value every 100 milliseconds.// - `skipN(10)` creates a filter that allows only every 10th value to pass through.const$oneSecStream=Stream.fromInterval(100).filter(skipN(10));// - The stream will print emitted values until the emitted value is 50, then unsubscribes.// - Once unsubscribed or naturally completed, the completion handler is executed.$oneSecStream.subscribe({next: (tick)=>{console.log(tick);if(tick>=50)$oneSecStream.unsubscribe?.();},complete: ()=>{console.log('stream concluded');},});

Combine two streams

// Emit a tuple of values every 500 millisecond//// - `Stream.fromInterval(500)` creates a stream that emits a value every 500 milliseconds.// - `Stream.fromInterval(1000)` creates a stream that emits a value every 1 second.// - withLatestFrom combines both the Streams.const$halfSecStream=Stream.fromInterval(500);const$mixedTimerStream=Stream.fromInterval(1000).withLatestFrom($halfSecStream);$mixedTimerStream.subscribe({next: ([halfSecTick,oneSecTick])=>{console.log(halfSecTick,oneSecTick);if(halfSecTick>=5)$mixedTimerStream.unsubscribe?.();},complete: ()=>{console.log('stream concluded');},});
