JavaScript 类型化数组 toSorted() 方法


示例

// 创建类型化数组
const myArr = Int32Array.of(40, 100, 1, 5, 25, 10);

// 将数组排序到一个新数组中
const newArr = myArr.toSorted();

更多示例如下!


描述

toSorted() 方法将数组元素排序到一个新数组中。

toSorted() 方法不会更改原始数组。

类型化数组排序方法:

方法 查找
reverse() 反转数组中元素的顺序
sort() 对数组中元素进行排序
toReversed() 将数组元素反转到一个新数组中
toSorted() 将数组元素排序到一个新数组中

语法

typed-array.toSorted(compareFunction)

参数

参数 描述
compareFunction 可选。

定义排序顺序的函数。该函数应根据参数返回负值、零或正值:

function(a, b){return a-b}

注意

普通数组按字母顺序排序。类型化数组按数字顺序排序。

因此,类型化数组通常不需要比较函数。

返回值

类型 描述
类型化数组 一个已排序的新数组。

降序排序

排序后反转顺序:

// 创建类型化数组
const myArr = Int32Array.of(40, 100, 1, 5, 25, 10);

// 将数组排序并放入新数组中
const newArr = myArr.sort();

// 反转新数组
newArr.reverse();
亲自试一试 »

使用比较函数按降序排序:

// 创建类型化数组
const myArr = Int32Array.of(40, 100, 1, 5, 25, 10);

// 使用函数对数组进行排序const newArr = myArr.toSorted(function(a, b){return b - a});

找出最小值

找出最小值:

// 创建类型化数组
const myArr = Int32Array.of(40, 100, 1, 5, 25, 10);

// 将数组排序到一个新数组中
const newArr = myArr.toSorted();

Get the lowest value
let lowest = newArr.at(0);
亲自试一试 »

找出最大值:

// 创建一个数组
const myArr = Int32Array.of(40, 100, 1, 5, 25, 10);

// 将数组排序到一个新数组中
const newArr = myArr.toSorted();

Get the highest value
let highest = newArr.at(-1);
