如何动态插入javascript对象?

Question

我有这个对象:

let ob1 = {
"2021-08-10": {
"A0304": {
"48": 1000
},
"A0301": {
"4": 1000,
"30": 1000,
"40": 1000
}
},
"2021-08-11": {
"A0301": {
"4": 1000
}
}
}

，我想插入另一个对象，比如

"2021-08-13": {"A0301": {4: 1000}

使用

let new =  {'2021-08-13': {'A0301': { 4: 'Hallo'}}}; 
Object.assign(obj1,new);`

工作好。但我想把它改成动态的，比如:

let new =  {app.desire.date: {app.desire.slot: { app.desire.slot: 'Hallo'}}}; 

但是通过定义new，我得到错误:Uncaught SyntaxError: missing: after property id

怎么做呢?

尝试使用[app.desire.date]

let obj1   = {
"2021-08-10": {
"A0304": {
"48": 1000
},
"A0301": {
"4": 1000,
"30": 1000,
"40": 1000
}
},
"2021-08-11": {
"A0301": {
"4": 1000
}
}
}
const newNode = { '2021-08-13': { 'A0301': { 4: 'Hallo' } } };
Object.assign(obj1, newNode);
var app = {
desire: {
date: '2021-08-14',
slot: 'A0301',
key: 4
}
}
let newNode2 = {
[app.desire.date]: {
[app.desire.slot]: {
[app.desire.key]: 'Hallo'
}
}
};
Object.assign(obj1, newNode2);
console.log(obj1)
