我正在尝试按最低数量 amoutinINR 键对医院数组进行排序，但我坚持对医院的深层嵌套 Object array 进行排序。任何伙伴都有知识 如何在没有任何第三方库(如 lodash 或 underscore)的情况下进行排序。
这是我的 JSON 对象。我正在尝试这样解决
// My first attempt
for (let i = 0; i < result.length; i++) {
for (let j = 0; j < result[i].procedure.length; j++) {
for (let k = 0; k < result[i].procedure[j].hospital.length; k++) {
if (k === 0 || k === 1 || k === 2) {
result[i].procedure[j].hospital[k].amountinDoller = `<b> ${hospitalDol.amountinDoller || 'N/A'} </b>`;
result[i].procedure[j].hospital[k].amountinINR = `<b>${hospitalInr[k].amountinINR || 'N/A'} </b>`
}
}
}
}
---------------------------------------------------------------------------------------
// here i am using map() native method of javascript
** my Second Attempt**
result.map((category,index) => {
return category.procedure.map((procedures,index) => {
return procedures.hospital.sort((a,b) => { return a.amountinINR - b.amountinINR});
})
});
// JSON Object
let result = [{

我想按最低的 amoutinINR 值对医院进行排序，并返回相同的 JSON 对象，其中包含已排序的医院。拜托，任何人都可以帮助我如何通过优化代码来实现吗？
最佳答案
基本上，您可以使用 Array#sort 对 result 中的每个数组进行排序并用 Array#forEach 迭代，因为您的 map 不返回任何内容。
result.forEach(r => r.procedure.forEach(p => p.hospital.sort((a, b) => a.amountinINR - b.amountinINR)));
