prefer-correct-switch-length

added in: 1.3.0
style
⚙️

Warns when a switch has too few or too many cases.

Use min-length configuration (default is 3), if you want to set the minimum number of cases.

Use max-length configuration (default is 10), to set up the maximum number of cases after which the rule should trigger.
