如何利用js语法打印菱形

javascript语法如何在控制台中打印出菱形图像，下面web建站小编给大家简单介绍一下！

具体代码如下：

function printDiamond(n) {
  if (n % 2 === 0) {
    n++;
  }
  let middleIndex = Math.floor(n / 2); 
  let diamond = ""; 
 
  for (let i = 0; i <= middleIndex; i++) {
    for (let j = 0; j < middleIndex - i; j++) {
      diamond += " "; 
    }
    for (let j = 0; j < 2 * i + 1; j++) {
      diamond += "*";
    }
    diamond += "
	"; 
  }
 
  for (let i = middleIndex - 1; i >= 0; i--) {
    for (let j = 0; j < middleIndex - i; j++) {
      diamond += " "; 
    }
    for (let j = 0; j < 2 * i + 1; j++) {
      diamond += "*";
    }
    diamond += "
	";
  }
  console.log(diamond);
}

输出结果：

console.log('输出图像：', printDiamond(5))
