Around the 2:40 mark, Jeremy says: "This is how I learn to code. I often know what I want to do but I don't always know how to do it. That gives me an opportunity to figure it out."
I know some JavaScript already, but I'm having this feeling so much with C#. It reminds me of the first time I was trying to understand how a for loop works. I knew what it was doing, I could describe it, and yet I still somehow couldn't wrap my head all the way around it. I know one day it'll all make sense and I'll wonder what was wrong with me for not understanding it yet.
I'm trying to build a Console app for Black Jack. Here is how I would describe parts of it in plain English:
- There is a Card . It has a rank and suit. It can be Deal 't from a Deck into a Hand.
- There is a Player which can Hit, Stand, Bet/Ante, and has Cards/Hands. There will be a HumanPlayer and a ComputerPlayer. The HumanPlayer will make an active choice on whether to Hit, Stand, or Bet. The ComputerPlayer will be automated based on the situation (Stand on 17 or higher; Hit on 16 or lower)
- There is a Deck made up of Cards. It can be Create 'd, Shuffle 'd, and Deal 't.
- There is a Hand, which is made up of Cards and can be Calculate 'd for the Total. The calculations will be by the value of number cards; Jacks, Queens, and Kings will count as 10; Aces will be counted as 11 or 1 based on whether the Total would put it above 21. If a Hand goes over 21, it's a Bust and that Player loses. Whichever player has the higher Total for its Hand would win the game.
- There is Money which belongs to each player. The players can Bet that Money, but not more than they currently have.

231,275 PointsBased on your description, I might imagine that a Hand might have an "Add" method that takes a Card argument, and a Deck might have a "Deal" method that returns the top card. So:
Player.Hand.Add(TheDeck.Deal()); // deal the top card into the player's hand
if (Player.Hand.Total > 21) { // oops! Bust
But you could also have "Deal" take an argument that is which hand to add to, and have it call "Add" directly instead of returning the dealt card:
TheDeck.Deal(Player.Hand);
So you have implementation options. Do what makes the most sense to you.

231,275 PointsYour strategy for building your app sounds good. But are you just sharing, or did you have a question about it?
