1. This file declares a class, Player, instantiates it, and assigns it to a global player variable.
2. The Player class contains four methods:
   • constructor()
   • playPause()
   • skipTo()
   • setVolume()
3. The constructor() method sets initial values for the currentlyPlaying, playState, volume, and soundObject properties.
   • currentlyPlaying is set to the first item in album.songs.
   • The initial playState is "stopped".

• The volume is set to the number 80.

Per the body of this Bloc checkpoint, here are the two requested message assignments.

Note: this does not include the actual assignments listed under the Assignement tab. I will include those details in my final Submission.

If I were to write a method that executes the functionality of an actual toaster, it might read something like this:

Reading RSpec:

There are flexible and dynamic ways to test code using test frameworks. One of the most popular frameworks in the Ruby on Rails community is RSpec.

• Important concept: a spec is running the code and testing to find out what happens.
• RSpec runs the code with particular conditions and with particular arguments.
• It sets expectations for the outcome of this test, and the test passes if those expectations are met.
• It's unreasonbale to think a programmer could manually test the code as their programm grows because that would mean testing every method anytime any little thing changes.
• Testing frameworks like RSpec automate the process of testing the code based on expectations set by the programmer.

Ruby: Arrays

Concept	Description
Array	An object that represents a collection of objects
Access	To access an element at a particular index, pass the index inside square brackets like array_name[0]. Use negative numbers to retrieve elements from the right to the left starting at -1
Insertion	To add an element to an existing Array object using methods like push, <<, unshift, insert
Removal	To remove elements from an Array object using methods like pop, shift, clear, delete
Sorting	We can sort a collection by calling the sort method on an Array object

Ruby: Classes 2

Concept	Description
Class	methods Behaviors that the class needs to implement that should not be direct responsibilities of the instances it creates. In a BankAccount class, this could be a method that calculates the average balance across all BankAccount objects
Constants	Variables that contain data that will not change and is shared amongst the instances of a class.
self	self refers to that which the method was called on. If used in a method signature/header before the method name, it makes the method a class method. If used inside an instance method, it refers to the instance the method was called on
Inheritance	Refers to the concept of extending a class by defining a subclass. The subclass inherits the attributes and behaviors of the parent class while keeping the ability to either override parent methods or create their own
super	super Can be used inside of a subclass method overriding a parent method. It will use the implementatio

Ruby: Loops

Concept	Description
Iteration	To traverse or visit every element in an Array object
each	The each method can be called on an Array object to iterate over the elements it contains
each_with_index	Allows for an additional variable to be used in the pipe operators that will represent the index of the current element
map	Can be used to iterate over every element in an Array while applying a method to each instance
Loop constructs	A loop construct allows for iteration of an object for a given number of times or while a condition is met

Ruby: Hashes

Concept	Description
Hash	A unordered data structure that allows for storage of key and value pairs
Access	We can access the value of a given key by passing the key to the hash like hash_name[:key]
Iteration	We can use a for in loop to iterate over the key/value pairs in a hash
Hash arguments	We can use hashes to pass arguments to a method call
