javascript - Node JS 将二维数组显示为网格

Question

这里是在 Node.js 中制作一个二维数组作为 conways 生命游戏棋盘的代码。我在显示主板时遇到问题。输出如下所示。

['-','-','-'] 
['-','-','-']
['-','-','-']

但是我希望它看起来像这样

这是现在的代码。有人有什么建议吗？

var createBoard = (width, height) => {
    board = [];
    row = [];
    for (var i = 0; i < width; i++) {
        for (var j = 0; j < height; j++) {
            row.push("-");
        }
        board.push(row);
        row =[];
    }
    return (board);
}

var displayBoard = (board) =>{
    for (var i = 0; i < board.length; i++) {
        console.log(board[i]);
    }
}

gameBoard = createBoard(3,3);
displayBoard(gameBoard);

您需要join数组的元素形成一个字符串。

var createBoard = (width, height) => {
    board = [];
    row = [];
    for (var i = 0; i < width; i++) {
        for (var j = 0; j < height; j++) {
            row.push("-");
        }
        board.push(row);
        row = [];
    }
    return (board);
}

var displayBoard = (board) => {
    for (var i = 0; i < board.length; i++) {
        console.log(board[i].join(""));
    }
}

gameBoard = createBoard(3, 3);
displayBoard(gameBoard);
