Code:

01 const sayHello = (name) = > {

02 console.log( ' Hello ' , name);

03 };

04

05 const world = () = > {

06 return ' World ' ;

07 };

08

09 sayHello(world);

This does not print " Hello World " .

What change is needed?

A. Change line 2 to console.log( ' Hello ' , name());

B. Change line 7 to }();

C. Change line 9 to sayHello(world)();

D. Change line 5 to function world() {

A developer wants to advocate for a mature, well-supported web framework/library instead of a new one (Minimalist.js).

Which two should be recommended?

A. React

B. Koa

C. Vue

D. Express

Refer to the following code (correcting the missing template literal backticks):

let codeName = ' Bond ' ;

let sampleText = `The name is ${codeName}, Jim ${codeName}`;

A developer is trying to determine if a certain substring is part of a string.

Which three code statements return true?

A. sampleText.includes( ' Jim ' );

B. sampleText.includes( ' The ' , 1);

C. sampleText.includes( ' Jim ' , 4);

D. sampleText.indexOf( ' Bond ' ) !== -1;

E. sampleText.substring( ' Jim ' );

Refer to the following code block (with corrected template literals using backticks):

01 class Animal {

02 constructor(name) {

03 this.name = name;

04 }

05

06 makeSound() {

07 console.log(`${this.name} is making a sound.`);

08 }

09 }

10

11 class Dog extends Animal {

12 constructor(name) {

13 super(name);

14 this.name = name;

15 }

16 makeSound() {

17 console.log(`${this.name} is barking.`);

18 }

19 }

20

21 let myDog = new Dog( ' Puppy ' );

22 myDog.makeSound();

What is the console output?

A. > Uncaught ReferenceError

B. > Undefined

C. > Puppy is barking.

Most accurate tests for:

const arr = Array(5).fill(0);

A. console.assert(arr.length === 0);

B. console.assert(arr[5] === 0 & & arr.length === 0);

C. arr.forEach(e = > console.assert(e === 0));

D. console.assert(arr.length === 5);
