我可以指定一个变量来检查循环中的多个数组吗？

Question

I am trying to check through multiple arrays inside of a loop, all with the same index. Instead of manually coding through every list I wanted to soft code it so every time the function loops it can check through all of my arrays. All of my arrays are named: score1-score8, but whenever this code runs it doesn't actually check any of the lists.

function checkHorizontal()
{

    var rowcount=0;
    var checkLists;
    var player1=0;
    var player2=0;

    checkLists="score"+rowcount;

    for (var i = 0; rowcount <= 8; i++) 
    {
        rowcount+=1;
        if(checkLists[rowcount]==1) 
        {
            player1+=1;
            player2=0;    
        }
        else if (checkLists[rowcount]==2)
        {
            player2+=1;
            player1=0;
        }

    }

}

Instead of giving each score a variable name that has an index, you can save the scores in an array and use another for loop.

Here's an example, assuming:

• We have two players
• A game consists of an unknown number of sets
• A set consists of an unknown number of legs

 const player1 = 1; const player2 = 2; const set1 = [ 1, 2, 1 ]; const set2 = [ 1, 2, 2 ]; const set3 = [ 2, 2, 1 ]; let player1Score = 0; let player2Score = 1; // Create a new array containing all sets: const game = [ set1, set2, set3 ]; // Loop over every set in the game for (let s = 0; s < game.length; s += 1) { const set = game[s]; // Loop over the legs in every set for (let g = 0; g < set.length; g += 1) { const winner = set[g]; if (winner === player1) player1Score += 1; if (winner === player2) player2Score += 1; } } console.log(`The final match score is player1 ${player1Score} vs player2 ${player2Score}`); 

For your specific case, you could define game as [ score1, score2, score3, score4, score5, score6, score7, score8 ]

If the number of players can also differ, you could add them to an array as well! You'd get a third loop, checking to which player you need to assign a point for every leg you process.
