NEW QUESTION # 137
Refer to the code below:
01 let first = ' Who ' ;
02 let second = ' What ' ;
03 try {
04 try {
05 throw new Error( ' Sad trombone ' );
06 } catch (err) {
07 first = ' Why ' ;
08 throw err;
09 } finally {
10 second = ' When ' ;
11 }
12 } catch (err) {
13 second = ' Where ' ;
14 }
What are the values for first and second once the code executes?
Answer: B
Explanation:
Initial values:
* first = ' Who '
* second = ' What '
Execution:
Inner try/catch/finally:
* Line 05: throw new Error( ' Sad trombone ' );
* Control goes to the inner catch.
* Inner catch (lines 06-08):
catch (err) {
first = ' Why ' ;
throw err;
}
* first is set to ' Why ' .
* The error is rethrown.
* Inner finally (lines 09-11):
finally {
second = ' When ' ;
}
* finally runs whether or not there was an error.
* second becomes ' When ' .
After inner finally, the rethrown error continues to propagate to the outer catch.
Outer catch (lines 12-14):
} catch (err) {
second = ' Where ' ;
}
* Because the inner try rethrew, the outer catch runs.
* It sets second = ' Where ' .
Final values:
* first was changed to ' Why ' in the inner catch and never changed again.
* second became ' When ' in the inner finally, and then ' Where ' in the outer catch.
So:
* first is ' Why '
* second is ' Where '
Option B is correct.
Concepts: nested try/catch/finally, rethrowing errors, order of execution for catch vs finally, variable mutation through error propagation.
