Question
Having an issue with my code. Not sure how to view the program's output to see the error and when I submit it on Zybook it gives me an error saying "Error: SyntaxError: Invalid shorthand property initializer".
Code:
let games = {
lives = 3,
coins = 0,
get points() {
return this.coins * 10;
},
playerDies: function() {
if (lives > 0) {
lives - 1;
}
return this.lives;
},
newGame: function() {
lives = 3;
coins = 0;
return this.lives + this.coins;
}
};
console.log("lives = " + game.lives); // should be 3
console.log("coins = " + game.coins); // should be 0
console.log("points = " + game.points); // should be 0
game.coins = 2;
console.log("points = " + game.points); // should be 20
game.playerDies();
console.log("lives = " + game.lives); // should be 2
game.playerDies();
game.playerDies();
game.playerDies();
console.log("lives = " + game.lives); // should be 0
game.newGame();
console.log("lives = " + game.lives); // should be 3
console.log("coins = " + game.coins); // should be 0

Transcribed Image Text:6.18 LAB: JavaScript game object
Create an object called game in the script.js file.
• Add 2 properties: lives - initially 3, and coins - initially 0.
• Add a getter called points that returns coins
• Add a playerDies() method that subtracts 1 from lives if lives is greater than 0.
• Add a newGame() method that sets lives to 3 and coins to 0.
10.
The script.js file includes several console.log() statements, which should match the output below if the game object works correctly.
lives
coins
points

20
lives

It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…arrow_forwardWrite code that outputs variable numDogs as follows.
