This rule aims to create clearer code by disallowing the bad practice of creating a label that shares a name with a variable that is in scope.
Examples of incorrect code for this rule:
/*eslint no-label-var: "error"*/ var x = foo; function bar() { x: for (;;) { break x; } }
Examples of correct code for this rule:
/*eslint no-label-var: "error"*/ // The variable that has the same name as the label is not in scope. function foo() { var q = t; } function bar() { q: for(;;) { break q; } }
If you don’t want to be notified about usage of labels, then it’s safe to disable this rule.
This rule was introduced in ESLint 0.0.9.
