Overriding object properties

We made sure that the loop inside the function works and the current element of the player array is logged in the console. What’s next?

After each roll, we must increase the game points by the result of this roll. We get the following entry player.points + = roll result. How does it work?

Overriding properties

Properties of objects can not only be read, but also overridden, just like ordinary variables. Let’s go back to the cat object.

var cat = {
  name: 'Muffin',
  age: 5
};

cat.age++; // Increasing cat’s age by 1
console.log(cat.age) // Logs 6 in the console

cat.name = 'Rocky'; // Replacing name property value outside
console.log(cat.name); // Logs 'Rocky' in the console

Inside the loop, we’ll call the throwDice roll function, write the result to a variable and increase the game points of the current player by this value. To make it easier to track events in the game, we will log the roll result for each player in the console.

By the way,

As you already know, when we call the array[index], we get array element. In our case, this is a player object, from which we can read as from any other object using dot. Therefore, entry in the body of our loop array[index].key is the same as entry object.key when working with the object directly.

Goalscompleted

Inside the loop in the body of the function, remove element console log.
Within the loop, declare variable throwResult, which contains the result of one roll muffin.throwDice(quantity, quantity * 6);.
Increase the number of roll points for the current player players[i].points += throwResult;.
Log in the console the player’s name and the number of their game points players[i].name + ' rolled ' + players[i].points.
