const wizard = {
name: "Merlin",
health: 50,
heal(num1, num2) {
return (this.health += num1 + num2);
},
};
const archer = {
name: "Robin Hood",
health: 5,
};
console.log("first", archer);
wizard.heal.call(archer, 50, 30);

The only difference between call() and apply() is that instead of call() that just takes parameters 50, 30. However, apply that takes an array of parameters [50,30].
