When the data stored on an object is a function, we call that a method. A property is what an object has, while a method is what an object does.

We can include methods in our object literals by creating comma-separated key-value pairs. The key serves as our method’s name, while the value is an anonymous function expression.

const specialOps = {
  attack: function () {
    console.log("Our objective is to denazify Kyiv.")
  },
}

With the new method syntax introduced in ES6, we can omit the colon and the function keyword.

const specialOps = {
  attack() {
    console.log("Our objective is to denazify Kyiv.")
  },
}

Object methods are invoked by appending the object’s name with the dot operator followed by the method name and parentheses.

specialOps.attack()

// Our objective is to denazify Kyiv.
