Write while loop equivalent in elixir

[silverdr]

@benwilson512

here’s a non manual loop version:

Stream.repeatedly(&generate_name/0) |> Stream.take(16) |> Enum.find(&not_taken?/1)

This will return the first generated name that isn’t taken, OR quit after 16 tries. It will only generate as many names as are needed. Enumerable works great here too. Of course, you can always use manual recursion.

Huh, that’s all so different from what I am well used to that after many years of successfully doing it for a living (using too many languages/stacks to list) I feel like I am learning programming from scratch again That’s both refreshingly challenging and intimidating at the same time. For example looking at the line, I wouldn’t guess that it will generate “only as many as needed”. Thanks.
