如何使用数组方法而不是'for loop‘来绘制正方形、矩形、十六进制的2D曲面？

const size = 5; // 正方形的边长
const square = Array.from({ length: size }, () => Array(size).fill('*'));
square.map(row => console.log(row.join(' ')));

const width = 5; // 矩形的宽度
const height = 3; // 矩形的高度
const rectangle = Array.from({ length: height }, () => Array(width).fill('*'));
rectangle.map(row => console.log(row.join(' ')));

const size = 5; // 曲面的大小
const hexSurface = Array.from({ length: size }, () =>
  Array.from({ length: size }, () => '#' + Math.floor(Math.random() * 16777215).toString(16))
);
hexSurface.map(row => console.log(row.join(' ')));
