OOP Game Challenge

Instructions:

• Create a constructor to create a Player object with a name
• Player should have a name as well as a lvl set to 1 by default and points set to 0 by default
• Create a method on the prototype called gainXp that takes in a number from 1-10 and adds it to the players points. If the current points are >= 10 then add 1 to the lvl and decrement the points by 10.
• Create another prototype method called describe that displays the players stats (name, lvl, points)

You should be able to use the Plyer object like this:

let player1 = new Player('Bob');
let player2 = new Player('Alice');

player1.gainXp(5);
player2.gainXp(7);
player1.gainXp(3);
player2.gainXp(2);
player1.gainXp(8);
player2.gainXp(4);

console.log(player1.describe()); // Bob is level 2 with 6 experience points
console.log(player2.describe()); // Alice is level 2 with 3 experience points

function Player(name) {
this.name = name;
this.lvl = 1;
this.points = 0;
}

Player.prototype.gainXp = function (xp) {
this.points += xp;
if (this.points >= 10) {
  this.lvl++;
  this.points -= 10;
}
};

Player.prototype.describe = function () {
return `${this.name} is level ${this.lvl} with ${this.points} experience points`;
};

let player1 = new Player('Bob');
let player2 = new Player('Alice');

player1.gainXp(5);
player2.gainXp(7);
player1.gainXp(3);
player2.gainXp(2);
player1.gainXp(8);
player2.gainXp(4);

console.log(player1.describe());
console.log(player2.describe());
