如果长度> 5，如何修剪数组

How to trim the array if length is > 5

我的JSON是:

{
        "name": "aaa"
        "files": [
            {
                "name": "A",
                "link": "string.com"
            },
            {
                "name": "Q",
                "link": "string.com"
            },
            {
                "name": "M",
                "link": "string.com"
            },
            {
                "name": "New Filters Reports",
                "link": "string.com"
            },
            {
                "name": "U",
                "link": "string.com"
            }
        ],
        "titles": [
            "A",
            "B",
            "C",
            "D",
            "E",
            "F"
        ]
    }

我要检查标题"的长度是否大于5，它应该修剪5之后的值，并且应该在屏幕上仅显示5个标题.

I want to check if "titles" length is greater than 5, it should trim the values after 5 and should display only 5 titles on screen.

推荐答案

您可以为此使用slice.

You can use slice for that.

let trimmed = data.titles.slice(0, 5);
