What is the best approach for replacing numerous maps within an rxjs observable array?

Is there a more efficient way to retrieve only 3 items from an array?

If you have any suggestions, I would appreciate it! Thank you.

loadAsk!: Observable<any[]>;

this.loadAsk.pipe(
  map(arr => arr.sort(() => Math.random() - .5)),
  map((item: any[]) => [item[0], item[1], item[2]])
).subscribe(res => {
  //code
})

Answer №1

What is your goal in this situation? Are you aiming to extract only the initial 3 numbers? Utilizing a pipe or observable may not be necessary for this task.

result:any[] = [data[0], data[1], data[2]]
