Prefer not to use labels that share a name with a variable JS-0121
Bug risk
Minor
Create clearer code by disallowing the bad practice of creating a label that shares a name with a variable that is in scope.
Bad Practice
var x = foo;
function bar() {
x:
for (;;) {
break x;
}
}
Recommended
// 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;
}
}
