Salesforce Certified JavaScript Developer - Multiple Choice Sample Questions (Q56-Q61):

NEW QUESTION # 56
Which option is true about the strict mode in imported modules?

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract JavaScript knowledge:
In JavaScript, ES modules (files imported using import / export) have special semantics:
All code inside a module is automatically executed in strict mode.
This is specified by the ECMAScript standard and does not require the explicit "use strict"; directive.
Effects:
You do not need to write "use strict"; at the top of a module file.
You cannot turn strict mode off for module code.
All module top-level code is treated as strict.
Now evaluate each option:
Option A:
Add the statement use non-strict; before any other statements in the module to enable notstrict mode.
There is no use non-strict; directive in JavaScript.
The only directive recognized by engines is "use strict";.
You cannot explicitly enable a "non-strict" mode with such a string.
Option B:
Imported modules are in strict mode whether you declare them as such or not.
This matches the language specification.
ES modules are always in strict mode, automatically.
This is true.
Option C:
Add the statement use strict = false; before any other statements in the module to enable notstrict mode.
use strict = false; is not a directive; it is parsed as a normal expression, and does not affect strict mode.
There is no supported way to disable strict mode in modules.
Option D:
A developer can only reference notStrict() functions from the imported module.
There is no special notStrict() restriction in modules.
Functions exported/imported in modules are simply subject to strict mode rules like the rest of the module's code.
Therefore, the only correct statement is:
Study Guide / Concept Reference (no links):
ES modules (import / export)
Automatic strict mode in modules
"use strict"; directive for scripts vs modules
Inability to disable strict mode in ES module code

NEW QUESTION # 57
Refer to the code below (assuming Promise.race is intended):
let cat3 = new Promise(resolve =>
setTimeout(resolve, 3000, "Cat 3 completes")
);
Promise.race([cat1, cat2, cat3])
.then(value => {
let result = `${value} the race.`;
})
.catch(err => {
console.log("Race is cancelled:", err);
});
(Assuming cat1 and cat2 are similar to earlier examples: cat2 resolves fastest.) What is the value of result when Promise.race executes?

Answer: A

Explanation:
From earlier pattern (cars/cats race):
One promise resolves the fastest with "Car 2 completed" (or analogous "Cat 2 completes").
Promise.race resolves with the first settled promise's value.
In .then, value is "Car 2 completed" and:
let result = `${value} the race.`;
// "Car 2 completed the race."
Thus result is "Car 2 completed the race." → option A.

Refer to thecode below:
Const pi = 3.1415326,
What is the data type of pi?

Answer: B


NEW QUESTION # 59
Given the following code:
What is the output of line 02?

Answer: D


NEW QUESTION # 60
A developer imports:
import printPrice from '/path/PricePrettyPrint.js';
What must be true about printPrice for this import to work?

Answer: D

Explanation:
________________________________________
Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge 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'.
