使用Array.sort()方法和编写的比较函数对数组进行排序: 将比较函数作为参数传递给Array.sort()方法,即可对数组进行排序。 javascript let arr = [3, 1, 5, 2, 4]; arr.sort(compareDescending); console.log(arr); // 输出: [5, 4, 3, 2, 1] 测试排序结果: 运行上述代码,并检查输出是否按预期排序...
letscores = [9,80,10,20,5,70];// sort numbers in ascending orderscores.sort((a, b) =>a - b); console.log(scores); 输出: [5,9,10,20,70,80] 要以降序对数字数组进行排序,您只需要反转比较函数中的逻辑,如...
priceList.sort(function(a, b){returna - b; }); // Output: Ascending - 2,7,14,50,1000console.log("Ascending - "+ priceList);// sort() using arrow function expression// descending order priceList.sort((a, b) =>b - a); // Output: Descending - 1000,50,14,7,2console.log("D...
JS sort array in descending order In order to sort values in descending order, we need to provide a custom compare function. main.js let vals = [-3, 3, 0, 1, 5, -1, -2, 8, 7, 6]; let words = ['sky', 'blue', 'nord', 'cup', 'lemon', 'new']; vals.sort((a, b) ...

[...events].sort((a, b) =>(a - b >0) ?1: -1);constarr = [4,5,8,2,3]; arr.sort((a, b) =>(a - b >0) ?1: -1);// [2, 3, 4, 5, 8] desc / descending 降序 [...events].sort((a, b) =>(a - b >0) ? -1:1);constarr = [4,5,8,2,3]; ...
sort modes:* - random: random array order* - reverse: last entry will be first, first the last.* - asce: sort array in ascending order.* - desc: sort array in descending order.* - natural: sort with a 'natural order' algorithm. See PHPs natsort() function.** In addition, this ...
array排序javascript arrayslist排序 ArrayList中有一个sort排序方法,只要你实现了Comparator的接口,按照你自己的排序业务进行实现,你只要告诉这个接口按照什么类型进行排序就OK了。这种方式类似于设计模式中的策略模式,把流程划分好,具体的业务逻辑由用户指定。这时候我们需要带着问题去看看里面具体是如何实现的.....
