Write an Html Page that uses JavaScript Program to make a Blackjack Game.

I need to write an html file (P5.html) that uses JavaScript program to create a Blackjack game.

1. Blackjack Games Rules:

a. The object of the game is to "beat the dealer", which can be done in a number of ways:
• Get 21 points on your first two cards (called a blackjack), without a dealer blackjack;
• Reach a final score higher than the dealer without exceeding 21;
or • Let the dealer draw additional cards until his hand exceeds 21.

b. The player is dealt an initial two-card hand and add together the value of their cards.

c. The dealer (not the player) has to take hits until cards total 17 or more points.

d. Values: Jack, Queen and King is 10, Ace is either 1 or 11, and all other cards have the value of their number.

e. The order does not matter. For examples, get 13 points on “A + 2 + K “ and “K + 2 + A” .

This game needs to use images of cards to assign values and play the game.

How do I design this html page and how do I use Javascript to make the game work?
