///////////////////////////////// Writing Methods ////////////////////////////////

// As mentioned earlier, objects can have methods that we can invoke to perform some kind of function or action on the object

// Methods are stored as an object property, but are programmed by defining a new function to assign the property to

// To look at a few examples, we will use the employee object below:

// The employee object will represent an employee of our imaginary company, Katie Johnson.

// This object stores the information for employee Katie Johnson, with properties for her name, ID, phone number, address, hourly wage, and number of hours worked this week.

// The last property of the employee object will be the method called "printEmployeeInfo"

// The printEmployeeInfo method declares a new function that returns the employee ID and full name in a formatted order

// You'll notice that the method uses a new keyword we haven't worked with yet, "this"

// When used in an object method, the 'this' keyword refers to the object in context.

// On line 30, this.firstName is equivalent to saying employee.firstName:
let employee = {
  firstName: "Katie",
  lastName: "Johnson",
  employeeID: 295025,
  phone: 4560001234,
  address: "42 Wallaby Way",
  wage: 13.5,
  hoursWorked: 25,
  printEmployeeInfo: function() {
    return (
      "Employee #" +
      this.employeeID +
      " : " +
      this.firstName +
      " " +
      this.lastName
    );
  }
};

console.log(employee.printEmployeeInfo());

// Next, lets add a method to the employee object that calculates their weekly pay
// This method will be called "paycheck" and will return the product of the employee object's wage property and the employee object's hoursWorked property:

employee.paycheck = function() {
  return "$" + this.wage * this.hoursWorked;
};

// Now, we can invoke the paycheck method like so:

let income = employee.paycheck();
console.log(income);

// or:

console.log(
  "Employee #" +
    employee.employeeID +
    " worked " +
    employee.hoursWorked +
    " hours this week and earned " +
    employee.paycheck()
);

// Try updating the hoursWorked property to a number greater than 25, and invoking the paycheck method again:

employee.hoursWorked = 40;
console.log(
  "Employee #" +
    employee.employeeID +
    " worked " +
    employee.hoursWorked +
    " hours this week and earned " +
    employee.paycheck()
);

// Finally, lets write an employee contacy information method.

// The method will be named "contact" and will print the information to the console in this order:

// Employee #ID - Last Name, First Name , Phone: (###)-###-#### , Address: __________

employee.contact = function() {
  return (
    "Employee #" +
    this.employeeID +
    " - " +
    this.lastName +
    ", " +
    this.firstName +
    " , Phone: (" +
    this.phone.toString().slice(0, 3) +
    ")-" +
    this.phone.toString().slice(3, 6) +
    "-" +
    this.phone.toString().slice(6, 10) +
    " , Address: " +
    this.address
  );
};

// Now we can invoke this method and print its return statement to the console:
console.log(employee.contact());

///////////////////////// Exercises /////////////////////////
//1. Create a new object representing a pizza place's customer with the following properties: customerName(string), orderID(number), order(string), orderTotal(number), payed(boolean)
// assign appropriate values to each of the object's properties
//2. Declare a new method named printOrder that returns the object's properties in this format: "Order #(Customer ID goes here): (order goes here) = (order total goes here)"
//3. Invoke the method and print it to the console
//4. Declare a new method called "pay" that changes the value of the payed boolean property to True
//5. Declare a new method called "receipt" that uses a conditional to check if the customer has payed, and if so, and returns "(Customer Name) payed (order total) for order #(orderID)"
// If the customer has not payed, the method should return "Awaiting customer payment for order #(order ID)"
//6. Call the receipt method before calling the pay method to ensure the else statement is executed when necessary.

//////////Extra Exercises: 

//1. Create an object called me that stores information about you: add properties for your name, age, favorite food, and favorite emoji (from here: https://www.w3schools.com/charsets/ref_emoji.asp). 
// Add a method called printEmoji, which prints out the favorite emoji property. 
// Add another method which creates a new date object for today and your birthday, and uses an if statement to calculate whether you are over 16 or not (if you are print out your name, and "is over 16."/ If not, print out your name and "is under 16.")

//2. Create an object called me2. Give it the properties name, birthday, and currentDate. Give the birthday property a date object with the date of your birthday, and the currentDate a date object with todays date (just new Date()). 
//Create a method called birthdayMonth. 
//In an if statement, test if the month of your birthday is less than the current month, and if it is, return "I have had my birthday already this year". (you can use me.birthday.getMonth() and me.currentDate.getMonth() to compare the months). 
// If your birth month is the same as the current month, return "My birthday is this month." If it is more than the current month, return out "My birthday will be later this year."
//Invoke your method inside a console.log

// 3. Create an object called pet
// Give the pet the properties type, age, name, and fill them out with relevant data.
// Make a method within your object to create an alert with the information, "My pet is called_____. They are a _____. They are _____ years old."
// Invoke your method to make sure its working. 

//4. Create an object which contains the parameters highTemp and lowTemp. Set them equal to the high and low temperatures today (google it!)
//Create a method which returns the following text on your webpage: "The high temperature for today is:____. The low temperature for today is_____."
//Outside of your object, use document.querySelector to select the body of your webpage, and set the innerHTML equal to your method, so that the text displays on your webpage.
