Salesforce Certified JavaScript Developer (JS-Dev-101) Sample Questions (Q53-Q58):

NEW QUESTION # 53
A developer wrote the following code:
01 let x = object.value;
02
03 try {
04 handleObjectValue(x);
05 } catch(error) {
06 handleError(error);
07 }
The developer has a getNextValue function to execute after handleObjectValue(), but does not want to execute getNextValue() if an error occurs. How can the developer change the code to ensure this behavior?

Answer: B

Explanation:
Requirement:
* getNextValue() should run only if handleObjectValue(x) does not throw an error.
* If an error occurs, handleError(error) should run, and getNextValue() should be skipped.
Option B:
try {
handleObjectValue(x);
getNextValue();
} catch (error) {
handleError(error);
}
Behavior:
* If handleObjectValue(x) succeeds (no error):
* Execution continues to getNextValue();.
* If handleObjectValue(x) throws:
* Control jumps directly to catch, getNextValue() is skipped.
* handleError(error); is called.
This matches the requirement perfectly.
Why others are incorrect:
* A: } then { is invalid JavaScript syntax.
* C:
try {
handleObjectValue(x);
} catch (error) {
handleError(error);
}
getNextValue();
* getNextValue() is called after the try...catch regardless of whether an error occurred. Not acceptable.
* D: finally always runs:
try {
handleObjectValue(x);
} catch (error) {
handleError(error);
} finally {
getNextValue();
}
* getNextValue() will execute in both success and error cases.
Therefore, the correct approach is B.
Concepts: try/catch control flow, finally semantics, placing code inside vs outside try/catch blocks.
