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.

Noncompliant Code Example

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
    }
}

Compliant Solution

function foo() {
    try {
        return 1; // We expect 1 to be returned
    } catch(err) {
        return 2; // Or 2 in cases of error
    }
}
