var array1 = [1, 30, 4, 21]; array1.sort() [1, 21, 30, 4] 但是如果是传一个compare 的function的话就变这样了. 升序 array1.sort((a, b) => a - b); // ascending 升序 [1, 4, 21, 30] 降序 array1.sort((a, b) => b - a) // descending 降序 [30, 21, 4, 1] /...
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...
Similarly, we can useb - ato sort them in descending order. Note that we can also use the arrow function expression defined in ES2015. We can also reverse (descending order) the sorted array using the built-in arrayreverse()method. To learn more, visitJavaScript Array reverse(). ...
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']; ...
[...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 ...

By combining sort() and reverse(), you can sort an array in descending order:Example const fruits = ["Banana", "Orange", "Apple", "Mango"]; fruits.sort(); fruits.reverse(); Try it Yourself » JavaScript Array toSorted() Method...
