NEW QUESTION # 118
A developer wants to use a module named universalContainersLib and then call functions from it.
How should a developer import every function from the module and then call the functions foo and bar?
Answer: D
NEW QUESTION # 119
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: C,D
Explanation:
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 โ Network โ "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 # 120
A developer has code that calculates a restaurant bill, but generates incorrect answers while testing the code:
function calculateBill (items ) {
let total = 0;
total += findSubTotal(items);
total += addTax(total);
total += addTip(total);
return total;
}
Which option allows the developer to step into each function execution within calculateBill?
Answer: A
NEW QUESTION # 121
What is the result of the code block?
Answer: A
NEW QUESTION # 122
A developer imports:
import printPrice from '/path/PricePrettyPrint.js';
What must be true about printPrice for this import to work?
Answer: C
Explanation:
The syntax:
import printPrice from 'module';
means the module must export its function as a default export:
export default function printPrice() { ... }
Why the others are wrong:
Named exports require curly braces:
import { printPrice } from 'module';
"all export" and "multi export" are not JavaScript terms.
Therefore, printPrice must be the default export.
JavaScript Knowledge Reference (text-only)
Default imports use: import name from 'module'.
Named imports require braces: import { name } from 'module'.
