如何使数组中的每个元素成为另一个数组？

I have some text that I receive from the user:

我有一些从用户收到的文字：

var text = ['Hello', 'World']; // this is the product of string.split(',')

I need to convert it into an array like this one:

我需要将它转换为像这样的数组：

var argument = [['Hello'], ['World']];

I need the input in this format so I can send multiple values to the db.

我需要这种格式的输入，所以我可以向db发送多个值。

How can I do this elegantly?

I can't think of anything more elegant for this than map:

我想不出比地图更优雅的东西：

E.g.:

例如。：

var argument = originalString.split(",").map(function(entry) {
    return [entry];
});

Or if you've enabled ES6 on your NodeJS installation:

或者，如果您在NodeJS安装上启用了ES6：

var argument = originalString.split(",").map((entry) => [entry]);
