Js localeCompare() 方法实现字符串数组排序

1语法：str.localeCompare(compareStr)

1'a'.localeCompare('b')  // 返回-1
2'b'.localeCompare('a')  // 返回 1
3'a'.localeCompare('a')  // 返回 0

1var fruits = ['pear','apple','peach','banana']
2var afterFruits = fruits.sort((a,b) => a.localeCompare(b))
3console.log(afterFruits) // ["apple","banana","peach","pear"]

1var names = ['方回','陈一','李四','陈波','张三','陈啊']
2var afterNames = names.sort((a,b) => a.localeCompare(b))
3console.log(afterNames) // ["陈啊", "陈波", "陈一", "方回", "李四", "张三"]

1var names = [{"name":"bb","sex":"男"},{"name":"aa","sex":"男"},{"name":"cc","sex":"女"},{"name":"bb","sex":"女"}]
2var afterNames = names.sort((a,b) => (a.name+a.sex).localeCompare(b.name+b.sex))
3console.log(afterNames) // [{"name":"aa","sex":"男"},{"name":"bb","sex":"男"},{"name":"bb","sex":"女"},{"name":"cc","sex":"女"}]
