NEW QUESTION # 113
Given the code:
01 function GameConsole(name) {
02 this.name = name;
03 }
04
05 GameConsole.prototype.load = function(gamename) {
06 console.log( ' ${this.name} is loading a game: ${gamename}.... ' );
07 }
08
09 function Console16bit(name) {
10 GameConsole.call(this, name);
11 }
12
13 Console16bit.prototype = Object.create(GameConsole.prototype);
14
15 // insert code here
16 console.log( ' ${this.name} is loading a cartridge game: ${gamename}.... ' );
17 }
18
19 const console16bit = new Console16bit( ' SNEGeneziz ' );
20 console16bit.load( ' Super Monic 3x Force ' );
What should a developer insert at line 15?

Answer: B

Explanation:
A subclass created by:
Console16bit.prototype = Object.create(GameConsole.prototype);
inherits all prototype methods from GameConsole, including load.
To override the inherited method, the correct syntax is to assign a new function to the method name on the prototype:
Console16bit.prototype.load = function(gamename) {
console.log(`${this.name} is loading a cartridge game: ${gamename}....`);
};
Why the other options are wrong:
* A assigns something to the constructor function itself, not to the prototype method. Invalid.
* B attempts to call a function in the left-hand side of an assignment; invalid syntax.
* C also uses invalid syntax-prototype methods cannot be defined this way.
* D is the correct definition of a prototype method override.
JavaScript Knowledge References (text-only)
* Methods are overridden by assigning functions to Subclass.prototype.methodName.
* Object.create() establishes prototype inheritance.
* Constructor functions require prototype method attachment using assignment syntax.


NEW QUESTION # 114
Refer to the code below:
Let car1 = new Promise((_ , reject) =>
setTimeout(reject, 2000, "car 1 crashed in" =>
Let car2 =new Promise(resolve => setTimeout(resolve, 1500, "car 2 completed")
Let car3 =new Promise(resolve => setTimeout(resolve, 3000, "car 3 completed")
Promise.race(( car1, car2, car3))
.then (value => (
Let result = '$(value) the race.';)}
.catch(arr => {
console.log("Race is cancelled.", err);
});
What is the value of result when Promise.race executes?

Answer: B
