Rule: no-duplicate-variable
Disallows duplicate variable declarations in the same block scope.
This rule is only useful when using the var
keyword -
the compiler will detect redeclarations of let
and const
variables.
Rationale
A variable can be reassigned if necessary - there’s no good reason to have a duplicate variable declaration.
Config
Not configurable.
Examples
"no-duplicate-variable": true
