How to use the sort () method in JavaScript

Editor to share with you how to use the sort () method in JavaScript, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Sort ()

If srot () takes no arguments, it sorts the elements in the array alphabetically, that is, in the order in which the characters are encoded.

If the number type is not sorted normally from smallest to largest, it is more like sorting by the size of the first digit of the element.

If you want to sort from big to small, from small to big. This can be achieved by comparing the size of the value.

From small to large, the meaning of a murb: a murb is greater than 0, which means that an is large, then put an after. If a color b is less than 0, it means that b is large, then b is later. If amurb equals 0, it remains the same. From big to small is the opposite of the above, do not say (do not want to write, the virtue of programmers is lazy)

As for why it is a-b _ r _ r _ b-a, you can read this article https://www.yisu.com/article/238275.htm
