Interview: endWith() a final marker

After the task value, add a final done marker.

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 { of, endWith } = Rx;

const result$ = of('task').pipe(
  endWith('done')
);

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