推荐答案

从MDN文档获取

From MDN docs for Number.prototype.toLocaleString():

格式化大量数字时，最好创建一个NumberFormat对象并使用其NumberFormat.format属性提供的功能.

When formatting large numbers of numbers, it is better to create a NumberFormat object and use the function provided by its NumberFormat.format property.

在大多数情况下，您可以使用Number.prototype.toLocaleString().它更易于使用，因为它允许您使用一个函数调用来格式化数字. Intl.NumberFormat仅在您要格式化大量数字时才有用.

In most cases you can use Number.prototype.toLocaleString(). It's simpler to use, because it allows you to format a number using one function call. Intl.NumberFormat is useful only when you want to format a large amount of numbers.
