NEW QUESTION # 53
A developer is leading the creation of a new web server for their team that will fulfill API requests from an existing client. The team wants a web server that runs on Node.js, and they want to use the new web framework Minimalist.js. The lead developer wants to advocate for a more seasoned back-end framework that already has a community around it.
Which two frameworks could the lead developer advocate for?
Answer: A,C
Explanation:
The question is about:
Web frameworks that run on Node.js
Used to build servers and APIs
With established communities.
From the given options:
Angular:
A front-end framework running in the browser, not a Node.js server framework.
Gatsby:
A React-based static site generator; uses Node tooling but is not primarily a Node server framework.
Next / Next.js:
Server-side rendering / full-stack frameworks built on Node.js and React.
Used to create both server-rendered pages and APIs.
They have active communities and are "seasoned" compared to a hypothetical Minimalist.js.
Although typical Node back-end frameworks would include Express.js, Koa, or NestJS, given the options provided, the best fits for server-side frameworks with Node.js and an ecosystem are:
Next (interpreted as Next.js)
Next.js
Thus, the correct pair from the list is B and D.
Concepts: Node.js web frameworks, server-side rendering, community-backed frameworks vs minimal/new frameworks.
NEW QUESTION # 54
A developer writes the code below to return a message to a user attempting to register a new username. If the username is available, a variable named msg is declared and assigned a value on line 03.
```javascript
function getAvailabilityMessage(item) {
if (getAvailability(item)) {
var msg = "Username available";
return msg;
}
}
Answer: D
NEW QUESTION # 55
Most accurate tests for:
const arr = Array(5).fill(0);
Answer: C,D
Explanation:
The correct answers are C and D.
The statement:
const arr = Array(5).fill(0);
creates an array with 5 elements, and every element is filled with the value 0.
So the array becomes:
[0, 0, 0, 0, 0]
A professional test should verify both important expectations:
arr.length === 5
and:
each element === 0
Option C is correct because it checks every element in the array:
arr.forEach(e => console.assert(e === 0));
This confirms that each array element was filled with 0.
Option D is correct because it checks the array length:
console.assert(arr.length === 5);
This confirms that the array contains exactly five elements.
Option A is incorrect because the array length is not 0; it is 5.
Option B is incorrect for two reasons. First, arr[5] is outside the valid index range. The valid indexes are:
0, 1, 2, 3, 4
So:
arr[5]
returns:
undefined
Second, arr.length === 0 is false because the length is 5.
Therefore, the verified answers are C and D.
NEW QUESTION # 56
Which two console logs output NaN?
Answer: C,D
Explanation:
Recall:
NaN stands for "Not-a-Number".
Arithmetic involving non-numeric values that cannot be converted to numbers often results in NaN.
Check each:
A . 10 / 0
In JavaScript, dividing a positive number by 0 results in Infinity, not NaN.
So this logs Infinity.
B . parseInt('two')
parseInt tries to parse a numeric prefix from the string.
'two' does not start with numeric digits, so parseInt('two') returns NaN.
The console log prints NaN.
C . 10 / Number('5')
Number('5') โ 5.
10 / 5 โ 2.
Logs 2, not NaN.
D . 10 / 'five'
'five' is coerced to a number using Number('five'), which is NaN.
10 / NaN โ NaN.
Logs NaN.
So the console logs that output NaN are from B and D.
Relevant concepts: NaN, Infinity, parseInt, Number() coercion, arithmetic with invalid numeric values.
NEW QUESTION # 57
01 function Animal(size, type) {
02 this.type = type || 'Animal';
03 this.canTalk = false;
04 }
05
06 Animal.prototype.speak = function() {
07 if (this.canTalk) {
08 console.log("It spoke!");
09 }
10 };
11
12 let Pet = function(size, type, name, owner) {
13 Animal.call(this, size, type);
14 this.size = size;
15 this.name = name;
16 this.owner = owner;
17 }
18
19 Pet.prototype = Object.create(Animal.prototype);
20 let pet1 = new Pet();
Given the code above, which three properties are set for pet1?
Answer: B,C,E
Explanation:
When pet1 = new Pet(); is created:
Inside Pet constructor:
Animal.call(this, size, type);
this.size = size;
this.name = name;
this.owner = owner;
Animal.call(this, size, type):
Sets this.type = type || 'Animal' โ 'Animal' (because type is undefined).
Sets this.canTalk = false.
Then this.size, this.name, this.owner are set (to undefined since no args passed), but they do exist as properties.
So as own properties, pet1 has: type, canTalk, size, name, owner.
speak is defined on Animal.prototype, so pet1.speak exists by inheritance, but is not an own data property created in the constructor.
From the listed options, three important properties directly set by constructor logic and clearly used in behavior are:
canTalk
name
type
Thus, C, D, E.
