suits.length)];
const randomRank = ranks[Math.floor(Math.random()
ranks.length)];
return suit: randomSuit, rank: randomRank ;“`
Evaluating High-Low Choice
This function will be the core of the player’s decision-making process. It compares the current card with the previous card and determines if the player’s guess (high or low) was correct.“`javascriptfunction evaluateHighLow(currentCard, previousCard, playerGuess) const currentRankValue = getRankValue(currentCard.rank); const previousRankValue = getRankValue(previousCard.rank); if (playerGuess === “high”) return currentRankValue > previousRankValue; else if (playerGuess === “low”) return currentRankValue < previousRankValue;
return false; // Invalid guess
```
Updating Game State
After each player’s turn, the game state needs to be updated.
This involves tracking the current card, the previous card, and the player’s score.“`javascriptfunction updateGameState(currentCard, previousCard, playerGuess, playerScore) const isCorrect = evaluateHighLow(currentCard, previousCard, playerGuess); if (isCorrect) playerScore += 10; else playerScore -= 5; return currentCard, previousCard, playerScore ;“`
Managing Player Scores
A structured approach to managing player scores is crucial. This section details the structure for storing and updating player scores throughout the game.“`javascriptlet playerScores = player1: 0, player2: 0,;“`
Handling Game Wins and Losses
The game needs to determine the winner based on the accumulated scores. The player with the highest score at the end wins.“`javascriptfunction determineWinner(playerScores) const player1Score = playerScores.player1; const player2Score = playerScores.player2; if (player1Score > player2Score) return “Player 1”; else if (player2Score > player1Score) return “Player 2”; else return “It’s a tie!”; “`
Reusable Modules
Breaking down the code into reusable modules promotes organization, maintainability, and scalability. Functions like `generateRandomCard`, `evaluateHighLow`, and `updateGameState` are ideal candidates for modularization.“`javascript// Example of a module structureconst gameLogic = generateRandomCard: function() // … (previous function code) , evaluateHighLow: function() // … (previous function code) , // …
other functions;“`
