Question

我正在学习Nodejs作为一个完整的初学者，并从重建Conway的生命游戏的任务开始。目前我只是希望能够在浏览器/控制台中绘制网格以便开始，但我遇到了一些困难。

我已经学习了一些教程，这是我到目前为止所提出的： main.js

var http = require(http);
var InitGrid = require('./InitGrid.js');

http.createServer(function (req, res){
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.write(console.log(InitGrid.InitGrid()));
    res.end();
}).listen(8080);

InitGrid.js

function make2DArray(GridWidth, GridHeight){

    let arr = new Array(GridHeight);

    for (let i=0; i < arr.length; i++){
        arr[i] = new Array(GridWidth);
    }
    return arr;
}

let grid;
let GridWidth = 50;
let GridHeight = 50;

function InitGrid() {

    grid = make2DArray(GridWidth, GridHeight);
    for (let i=0; i < GridWidth; i++) {
        for (let j=0; j < GridHeight; j++) {
            grid[i][j] = floor(random(2));
        }
    }

}

当我使用'node main.js'运行上面的代码时，我收到以下错误：

assert.js:42
  throw new errors.AssertionError({
  ^

AssertionError [ERR_ASSERTION]: missing path
