Enforce final break

[LinusU]

Would it make sense to enforce a break even in the last case statement within a switch? I think it's a good practice so that the next guy doesn't forget to add one in.

switch (_) {
  case 1:
    console.log('Hello')
    break
  case 2:
    console.log('world!')
    // standard would enforce a break here
}

Sure I'm fine with that. But I don't think ESLint has a rule for it, so it's probably not worth the effort. If you get a rule or option for this into ESLint, happy to enable it in the next major version if there's not too much breakage :)

But it's really not a risk if you're using standard since it will warn about "fall through" when the next programmer adds a new case and forgets to add break.

Going to close this since there's no ESLint rule for it. But feel free to send a PR when/if you get it added.
