大小写排列顺序

Question

假设我们有以下数组

let names = ['Malek', 'malek', 'sana', 'ghassen', 'Ghada', 'Samir']; 
console.log(names.sort()); 

结果如下：

["Ghada", "Malek", "Samir", "ghassen", "malek", "sana"]

JavaScript根据其ASCII值比较每个字符。

我想按小写字母排序在排序数组中排在首位，

预期的输出：

 ["Ghada", "ghassen", "malek", "Malek", "Samir", "sana"]

谢谢

Answer 1

使用localeCompare尝试一下：

const names = ["Ghada", "Malek", "Samir", "ghassen", "malek", "sana"];
const result = names.sort((a, b) => a.localeCompare(b)); 

console.log(result);

localeCompare（）方法返回一个数字，该数字指示该字符串按排序顺序位于compareString之前，之后还是相等。
