Lodash sortBy 以随机顺序返回元素（未排序）

Question

Lodash sortBy 对我不起作用：

const _ = require('lodash');
let array = [3, 'q', 'e', 'w', 4, 'w', 1, 3, 2];
let data = _(array).sortBy(x => x);
console.log(data.value());
console.log(array.sort());

输出

[ 3, 'e', 'q', 'w', 4, 'w', 1, 2, 3 ]
[ 1, 2, 3, 3, 4, 'e', 'q', 'w', 'w' ]

.sortBy() 的输出毫无意义。内置.sort() 按预期工作。我错过了什么？

Answer 1

您可以将项目转换为字符串以进行比较

let array = [{a:3}, {a:'q'}, {a:'e'}, {a:'w'}, {a:4}, {a:'w'}, {a:1}, {a:3}, {a:2}];
let data = _(array).sortBy(x => x.a.toString());
console.log(data);
