[英]how to sort deep nested object by value?
我正在尝试按最低金额amountinINR键对医院数组进行排序，但是我被困在对医院的深层嵌套Object array进行排序的过程中。
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amountinINR值对医院进行排序，并返回内部已排序医院的相同JSON对象。 请，有人可以帮助我如何通过优化的代码实现目标吗？
基本上，cou可以使用Array#sort对result每个数组进行Array#sort并使用Array#forEach进行迭代，因为您的映射不会返回任何内容。
result.forEach(r => r.procedure.forEach(p => p.hospital.sort((a, b) => a.amountinINR - b.amountinINR)));
答案与Nina Scholz基本相同，但使用的是旧方法。
