Variable is declared and being used in different 'case' clauses
Reports a variable that is declared in one case clause of a switch statement but is used in another case clause of the same statement. For block-scoped variables, this results in throwing a ReferenceError. For var variables, it indicates a potential error.
Disable the inspection for var variables if this pattern is used intentionally.
