I started an experimental series, "console.solve", on mini javascript challenges a few months back and received good feedbacks on it. So I created a [second one](<a href="https://colintoh.com/console-solve/issue-2?utm_source=colintoh&utm_campaign=hn&utm_medium=hn" rel="nofollow">https://colintoh.com/console-solve/issue-2?utm_source=colint...</a>) this month.
Not sure anyone here will be interested as it's not exactly pro-level stuff. But if you have an hour to spare, it can be a good distraction. For those who are interested, here was the [first challenge](<a href="https://colintoh.com/console-solve/issue-1?utm_source=colintoh&utm_campaign=hn&utm_medium=hn" rel="nofollow">https://colintoh.com/console-solve/issue-1?utm_source=colint...</a>).
