observable
// このメソッドを実行した Observable(`observable`)が通知する値(`2000`、`1000`、`3000`)に対して
// Observable に変換する関数(`v => Rx.Observable.timer(v).mapTo(v)`)を実行し、その戻り値を通知する Observable を生成する。
// 今回の場合、通知する戻り値は以下の3つの Observable。
// Rx.Observable.timer(2000).mapTo(2000)
// Rx.Observable.timer(1000).mapTo(1000)
// Rx.Observable.timer(3000).mapTo(3000)
.map(v => Rx.Observable.timer(v).mapTo(v))
.subscribe(
x => console.log(`next: ${x}`),
error => console.error(`error: ${error}`),
() => console.log('complete')
);
// => "next: [object Object]" [object Object]は Rx.Observable.timer(2000).mapTo(2000)
// => "next: [object Object]" [object Object]は Rx.Observable.timer(1000).mapTo(1000)
// => "next: [object Object]" [object Object]は Rx.Observable.timer(3000).mapTo(3000)
// => "complete"
