This article mainly introduces js how to achieve digital sorting, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Numeric sorting

By default, the sort () function sorts values in string order.

This function works well with strings ("Apple" comes before "Banana").

However, if the numbers are sorted by string, "25" is greater than "100" because "2" is greater than "1".

For this reason, the sort () method produces incorrect results when sorting values.

We correct this problem with a ratio function:

Example

Var points = [40,100,1,5,25,10]; points.sort (function (a, b) {return a-b})

Use the same technique to sort the array in descending order:

Example

Var points = [40,100,1,5,25,10]; points.sort (function (a, b) {return b-a}); Thank you for reading this article carefully.
