Split object into two and renumerate keys

Question

I would like to split an object into two parts according to property "amount" (empty string)

let myObj = {
"1": {
    "resources": "hotel",
    "amount": "",
    "currency": ""
},
"2": {
    "resources": null,
    "amount": "300.00",
    "currency": "CZK"
},
"3": {
    "resources": null,
    "amount": "500.00",
    "currency": "USD"
},

}

to this

obj1 = {
"1": {
    "resources": "hotel",
    "amount": "",
    "currency": ""
}}
obj2 = {
"1": {
    "resources": null,
    "amount": "300.00",
    "currency": "CZK"
},
"2": {
    "resources": null,
    "amount": "500.00",
    "currency": "USD"
}}

I'm close to solving it but after numerous attempts (push, assign, map) it still does not work. Thx.

You can acheive your goal like this:

let myObj = {
  "1": {
    "resources": "hotel",
    "amount": "",
    "currency": ""
  },
  "2": {
    "resources": null,
    "amount": "300.00",
    "currency": "CZK"
  },
  "3": {
    "resources": null,
    "amount": "500.00",
    "currency": "USD"
  },
}

const withAmount = {},
  withoutAmount = {};

Object.keys(myObj).forEach(key => {
  const item = myObj[key];
  if (item.amount) {
    withAmount[key] = item;
  } else {
    withoutAmount[key] = item
  }
})

console.log('withAmount:',withAmount)
console.log('withoutAmount:',withoutAmount)
