Object Methods

👨‍💼 Objects can contain functions! When a function is a property of an object, we call it a method.

const calculator = {
	add: function (a, b) {
		return a + b
	},
	// Shorthand syntax (preferred):
	subtract(a, b) {
		return a - b
	},
}

calculator.add(5, 3) // 8
calculator.subtract(5, 3) // 2

🐨 Open

index.js

and:

Create an object person with properties firstName and lastName
Add a method getFullName that returns the full name (firstName + lastName)
Add a method greet that returns "Hello, I'm [fullName]!"
Call both methods and log the results

💰 Inside a method, use this to refer to the object itself:

const person = {
	name: 'Alice',
	sayHi() {
		return 'Hi, I am ' + this.name
	},
}
