JavaScript defines two main page-loading events:
* DOMContentLoaded Fires when the HTML document has been completely parsed. External resources like images, stylesheets, iframe contents, etc. may not be loaded yet .
* load event on window Fires when:
* HTML is fully parsed
* All dependent resources (images, scripts, CSS, fonts, etc.) are fully loaded The requirement states:
"when the webpage is fully loaded (HTML content and all related files )" This aligns exactly with the window load event .
Implementation:
window.addEventListener( " load " , personalizeWebsiteContent);
This matches option B.
JavaScript knowledge references (text-only)
* DOMContentLoaded fires after HTML parsing only.
* load fires after all page resources finish loading.
* The window object is the correct target for listening to the full load event.

The correct answer is D .
Semantic versioning usually follows this format:
MAJOR.MINOR.PATCH
For the version:
1.1.3
The parts are:
1 = MAJOR
1 = MINOR
3 = PATCH
A package version should be updated based on the type of change:
MAJOR version changes when there are breaking changes.
MINOR version changes when new features are added in a backward-compatible way.
PATCH version changes when backward-compatible bug fixes are added.
The question says the developer added new features that do not break backward compatibility . That means the minor version should increase.
Starting version:
1.1.3
Increase the minor version from 1 to 2, and reset the patch version to 0:
1.2.0
Why the other options are incorrect:
A). 1.2.3 is incorrect because when the minor version increases, the patch version should reset to 0.
B). 1.1.4 is incorrect because that would represent a patch update, usually for bug fixes, not new features.
C). 2.0.0 is incorrect because that would represent a major version update, usually for breaking changes.
D). 1.2.0 is correct because it represents a backward-compatible feature release.
Therefore, the verified answer is D .

* execute() returns a Promise that immediately calls reject(). So promise starts in a rejected state.
* When a Promise is rejected and you chain .then() calls without rejection handlers, all those .then() callbacks are skipped until a .catch() is encountered:
promise
then(...) // skipped
then(...) // skipped
then(...) // skipped
catch(...) // executed
then(...); // executed after catch
* Execution:
* .then(() = > console.log( ' Resolved1 ' )) is skipped.
* .then(() = > console.log( ' Resolved2 ' )) is skipped.
* .then(() = > console.log( ' Resolved3 ' )) is skipped.
* .catch(() = > console.log( ' Rejected ' )) runs and logs Rejected.
* The .catch() returns a resolved Promise (no explicit return, so undefined), so the next .then() runs:
* .then(() = > console.log( ' Resolved4 ' )) logs Resolved4.
Final output:
Rejected
Resolved4
This matches option D.

The correct answer is B because countsDeep() is executed inside the callback function passed to setTimeout(), and the try...catch block is also placed inside that same callback.
In JavaScript, setTimeout() schedules a function to run later. The outer code finishes first, and the callback runs asynchronously after the delay. Because of this, a try...catch block placed outside setTimeout() cannot catch errors thrown later inside the callback.
Correct logic:
setTimeout(function() {
try {
countsDeep();
} catch (e) {
handleError(e);
}
}, 1000);
Here, when countsDeep() runs after 1000 milliseconds, any error thrown by countsDeep() happens inside the try block. Therefore, the catch (e) block can catch that error and pass it to handleError(e).
Why the other options are incorrect:
A is incorrect because the syntax is invalid JavaScript. A valid try...catch structure must be:
try {
// code
} catch (e) {
// handle error
}
Option A incorrectly writes:
} handleError (e){
catch(e);
}
That is not valid try...catch syntax.
C is incorrect because the try...catch surrounds only the call to setTimeout(), not the later execution of countsDeep(). If countsDeep() throws an error after the timer expires, the outer catch block will not catch it.
D is incorrect for the same reason as C. In the original question, D also had a typing error: it used countSheep() instead of countsDeep(). Even after correcting that typing error, D is still incorrect because the try...catch is outside the asynchronous callback.

Behavior of Promise.prototype.finally:
* .finally(handler) registers a callback that runs when the promise is settled , meaning:
* Either fulfilled (resolved) , or
* rejected .
Important points:
* The finally callback does not receive the promise's value or error (unlike then and catch).
* It is executed after the promise is settled, but before the resolution value or rejection reason is passed further down the chain.
* It runs in both success and failure paths.
In the given code:
* The promise may either:
* Call reject( ' fraction > 0.5, ' + fraction) if fraction > 0.5, or
* Call resolve(fraction) otherwise.
In both cases:
* If it resolves , .then(() = > console.log( ' resolved ' )) runs, and then .finally(...) is executed.
* If it rejects , .catch((error) = > console.error(error)) runs, and then .finally(...) is executed.
So .finally runs:
* Not just "when rejected".
* Not just "when resolved".
* But whenever the promise is resolved or rejected .
Therefore, the correct choice is:
* D. When resolved or rejected .
