No value is returned from the function '_onFocus' defined at line 91

[giorgosart]

From Deepscan:

Return value of function without any return statement should not be used

This rule applies when return value is used even though the function has no return statement.

In such a case, it could be a programmer's mistake forgetting a return statement.

Note: This rule applies only when the return value is assigned to an object property because in other cases, it is often intended or harmless.

Code Example
function add(x, y) {
    x + y;
}
obj.total = add(1, 2); // MISSING_RETURN_VALUE alarm because function 'add' does not return a value.
Revised Code Example
function add(x, y) {
    return x + y;
}
obj.total = add(1, 2);
