js 数组去除空字符串

要在JavaScript数组中去除空字符串，可以使用filter方法。首先，使用split方法将字符串分割成数组。然后，使用filter方法对数组进行拷贝，删除空字符串元素，保留其他元素。具体实现代码如下所示：

const array = ["", "Hello", "", "World", "", ""];

const newArray = array.filter((element) => {
  return element !== "";
});

console.log(newArray);  // 输出: ["Hello", "World"]

在上面的例子中，我们创建了一个包含空字符串的数组。然后，使用filter方法对数组进行拷贝，并通过判断元素是否为空字符串来删除空字符串元素。最后，打印新数组，即去除了空字符串的数组。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
