NEW QUESTION # 27
After user acceptance testing, the developer is asked to change the webpage background based on the user's location. It works on the developer's computer but not on the tester's machine.
Which two actions will help determine accurate results?
Answer: B,D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge:
Browsers often cache JavaScript, CSS, and HTML. This means:
The developer may be running with the latest version (often with cache disabled in DevTools).
The tester may still be loading an older, cached version of the page where the background-change logic does not exist.
To ensure they are actually testing the latest deployed code:
Disabling cache (A) in the tester's browser (usually via DevTools → Network → "Disable cache") forces fresh loading of all resources on each refresh.
Clearing cache (C) removes older resources from the browser so the next load fetches fresh files from the server.
Options B and D do not directly help verify the tester is using the latest code:
B checks the developer's own browser, which is not the environment showing the problem.
D suggests reworking the code before confirming whether the tester is actually loading the correct version, which is premature.
So the two actions that help produce accurate testing results are A and C.

NEW QUESTION # 28
A developer wants to use a module called DatePrettyPrint.
This module exports one default function called printDate().
How can the developer import and use printDate()?
Answer: B
Explanation:
________________________________________
Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge ES Modules follow these rules:
Default exports are imported using:
import anyName from 'module'
The name chosen in the import does NOT need to match the exported name.
If a module exports:
export default function printDate() {}
then consuming code should import the function directly:
import printDate from '/path/DatePrettyPrint.js';
To execute it:
printDate();
Option analysis:
A incorrect:
import DatePrettyPrint() is invalid syntax.
Also calling printDate() without importing it is incorrect.
B incorrect:
A default export imported as DatePrettyPrint gives the function itself, not an object containing methods.
You cannot call DatePrettyPrint.printDate().
C incorrect:
Imports printDate but then calls DatePrettyPrint.printDate(), which does not exist.
D correct:
Correct import of a default-exported function.
Correct direct invocation.
________________________________________
JavaScript Knowledge Reference (text-only)
Default export → imported without braces.
Importing default functions gives a callable function, not an object.
Correct syntax: import identifier from "module".
NEW QUESTION # 29
Refer to the code below:
01 <html lang="en">
02 <table onclick="console.log('Table log');">
03 <tr id="row1">
04 <td>Click me!</td>
05 </tr>
06 </table>
07 <script>
08 function printMessage(event) {
09 console.log('Row log');
10 event.stopPropagation();
11 }
12
13 let elem = document.getElementById('row1');
14 elem.addEventListener('click', printMessage, false);
15 </script>
16 </html>
Which code change should be done for the console to log the following when "Click me!" is clicked?
Row log
Table log
Answer: D
Explanation:
Current behavior:
Clicking <td> triggers the click event on row1, then bubbles up to <table>.
printMessage runs, logs "Row log", then event.stopPropagation() stops the event from bubbling to the table.
So "Table log" never appears.
To allow the table's inline onclick to run after the row handler:
Remove the propagation stop:
function printMessage(event) {
console.log('Row log');
// event.stopPropagation(); // remove this
}
Now the event bubbles:
printMessage logs "Row log".
The table's onclick runs, logging "Table log".
Option A only changes capture/bubble phase but still stops propagation. C does nothing meaningful (stopPropagation takes no arguments). B removes the row handler entirely.
NEW QUESTION # 30
A developer initiates a server with the file server.js and adds dependencies in the source code's package.json that are required to run the server.
Which command should the developer run to start the server locally?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From JavaScript/Node.js Knowledge:
In a Node.js project that uses package.json, you typically define a "start" script:
{
"scripts": {
"start": "node server.js"
}
}
Then you start the app with:
npm start
npm start:
Looks up the "start" script in package.json.
Runs the command defined there (commonly node server.js).
This is the standard way to start a Node.js app with npm-managed dependencies.
Why others are incorrect:
A . node start
Tries to run a file named start with Node; does not use package.json scripts.
C . npm start server.js
npm start does not take the script filename as an argument in this way; it just runs the start script as defined.
D . start server.js
Not an npm or node command; on some shells it just tries to "start" a process but is not the standard Node/npm workflow.
Relevant concepts: package.json, npm scripts, npm start, Node entry file execution.
