Real-life: from() for a list of orders

Turn an array of order ids into a stream and add the prefix order-.

1. Solve the task in the editor — no long theory.
2. Run the check and compare your output with the expected result.
3. Stuck? Open the solution and carry the approach into your own code.

const { from, map } = Rx;

const ids = [101, 102, 103];

const result$ = from(ids).pipe(
  map(id => 'order-' + id)
);

result$.subscribe(value => console.log(value));
