Validate a cron pattern without actually scheduling it

[mactyr]

As someone mentioned in this comment, it would be helpful to have a clean way to validate a cron pattern without actually scheduling it. I think I can get close enough currently by doing:

try {
  Cron(pattern, {stopAt: new Date()});
} catch (err) {
  // whatever I want to do if the pattern is invalid
}

But this is kind of messy and verbose relative to something like Cron.isValid(pattern) that would return a boolean.

Great idea 👍
