Using `+return+`, `+break+`, `+throw+`, and `+continue+` from a `+finally+` block overwrites similar statements from the suspended `+try+` and `+catch+` blocks.

|
|
This rule raises an issue when a jump statement (`+break+`, `+continue+`, `+return+` and `+throw+`) would force control flow to leave a `+finally+` block.

function foo() {

try {

return 1; // We expect 1 to be returned

} catch(err) {

return 2; // Or 2 in cases of error
|
|
} finally {
|
|
return 3; // Noncompliant: 3 is returned before 1, or 2, which we did not expect
