javascript - Javascript 的原生排序方法是如何工作的？

Question

[1, false, 10, "b", 3, "33", ":", "R", "^"].sort()

产生以下排序:

[1, 10, 3, "33", ":", "R", "^", "b", false]

谁能解释一下 sort 方法是如何工作的？我猜它一定是将所有内容都翻译成 ASCII。

当我这样做时情节变浓了

[1, false, 10, "b", 3, "33", ":", "R", "^"].sort(function(a,b) {return b-a})

输出如下:

[10, 1, false, "b", "33", 3, ":", "R", "^"]

有什么方法可以解决这种疯狂问题吗？

来自 MDN:

If compareFunction is not supplied, elements are sorted by converting them to strings and comparing strings in Unicode code point order.

和:

If compareFunction is supplied, the array elements are sorted according to the return value of the compare function.
