Merging two array of objects only when array element contains error - javascript

So I have two arrays with objects. And also an array indicating where the replacement should take place(It spots if object contains error)
const oldData = [

const errorRows = [0,1,3]
const myTerribleAttempt = oldTableData.map((oldData, rowIndex) => {
return errorRows.map(index => {
if(rowIndex === index){
newTableData.map(newData => {
oldData = newData
})
}
})
})
I have tried multiple maps and just can't seem to get the right result. The new data objects should replace old data objects at the object containing the error. Please give me some assistance.

I think you've overcomplicated this - just check if the index is contained in the error array and choose old or new data.
const result = oldData.map( (item, idx) => errorRows.includes(idx)
? newData[errorRows.findIndex(x => x == idx)]
: item);
live example:
const oldData = [{

How Can I... please help me
You could create a Map keyed by title and with the corresponding objects as values. Then use that map to retrieve for each object the parent object, and insert it in the parent's children array.
Here is how that could look:
const dbDataArray = [{"title": "Marvel","value": "1000","key": "1000","parentName": null,"children": []},{"title": "X-man","value": "1100","key": "1100","parentName": "Marvel","children": []},{"title": "Wolverine","value": "1110","key": "1110","parentName": "X-man","children": []},{"title": "Professor X","value": "1120","key": "1120","parentName": "X-man","children": []},{"title": "Avengers","value": "1200","key": "1200","parentName": "Marvel","children": []},{"title": "Captain America","value": "1210","key": "1210","parentName": "Avengers","children": []},{"title": "Peggy Carter","value": "1211","key": "1211","parentName": "Captain America","children": []},{"title": "Iron Man","value": "1220","key": "1220","parentName": "Avengers","children": []},{"title": "Tony Startk","value": "1221","key": "1221","parentName": "Iron Man","children": []},{"title": "War Machines","value": "1222","key": "1222","parentName": "Iron Man","children": []},{"title": "DC","value": "2000","key": "2000","parentName": null,"children": []},{"title": "BatMan","value": "2100","key": "2100","parentName": "DC","children": []},{"title": "SuperMan","value": "2200","key": "2200","parentName": "DC","children": []},]
const result = [];
const map = new Map(dbDataArray.map(o => [o.title, o])).set(null, {children: result});
for (const o of dbDataArray) map.get(o.parentName).children.push(o);
console.log(result);

merge multilevel json object to create stagged object with no loss of data

I want to merge two multi-level object to form a single object with no loss of data.
till the level data is same no extra fields should be added, at level where fields are different new object should get inserted in the array.
we have to group json object of similar fields in one complete json.
multilevel object needs to be merged together to get one aggragated result.
my sample objects are as -
let one={
"name": "Hindi",
"country": "USA",
"region": "EAST COAST",
"enttity": "ENTITY-2",
"operation": [
{
"p_name": "RECONSTRUCTION",
"code": "jhhkj-132",
"class": "medical",
"products": [
{
"main": "electronic",
"area": [
{
"subarea": "electrical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000514",
"number": "1588TB-1",
"description": "DESCRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
}
]
}
]
}
]
};
let two={
"name": "Hindi",
"country": "USA",
"region": "EAST COAST",
"enttity": "ENTITY-2",
"operation": [
{
"p_name": "RECONSTRUCTION",
"code": "jhhkj-132",
"class": "medical",
"products": [
{
"main": "electronic",
"area": [
{
"subarea": "mechanical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000523314",
"number": "1588T3B-1",
"description": "DES32CRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
},
{
"subarea": "electrical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000514",
"number": "1588TB-1",
"description": "DESCRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
}
]
}
]
}
]
};
output json should be something like this->
let outpus={
"name": "Hindi",
"country": "USA",
"region": "EAST COAST",
"enttity": "ENTITY-2",
"operation": [
{
"p_name": "RECONSTRUCTION",
"code": "jhhkj-132",
"class": "medical",
"products": [
{
"main": "electronic",
"area": [
{
"subarea": "mechanical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000523314",
"number": "1588T3B-1",
"description": "DES32CRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
},
{
"subarea": "electrical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000514",
"number": "1588TB-1",
"description": "DESCRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
}
]
}
]
}
]
};

JavaScript time comparison with arrays

I'm working on a project where I need to get all the vacant classrooms for the day and basically filter out the ones being in use.
I get all the data from the school's own API with JSON response body that looks like this:

In order to get the JSON response I need to put startDate (the moment user searches the vacant rooms, in this situation it is: 2017-04-27T10:55) and endDate (set to end of the day, 2017-04-27T22:00). The result for this query is the JSON response above.
The problem is that the API I'm using doesn't contain any data for the vacant rooms but only for the ones booked for certain times so I made a list of all the rooms in the building and compared it to the booked ones to filter them out:
var rooms = ['A120.3', 'A130.1', 'A130.3', 'A140.1', 'A140.2', 'A140.4', 'A250.1', 'A240.4', 'A240.2', 'A220.5', 'A220.3',
'A220.1', 'A210.2', 'A320.2', 'A320.6', 'A320.7', 'A320.8', 'A340.1', 'A340.2', 'A350.1', 'A350.3', 'A440.5', 'A450.3','A450.1',
'A440.4', 'A440.2', 'A420.6', 'A420.5', 'A420.4', 'A420.2', 'A510.2', 'A520.5', 'A510.4', 'A520.6', 'A520.7','A540.1', 'A540.2'];
var data = JSON.parse(responseText);
var booking = Object.create(null);
var free;
data.reservations.forEach(function (reservation) {
reservation.resources.some(function (resource) {
if (resource.type === 'room') {
booking[resource.code] = booking[resource.code] || [];
booking[resource.code].push({ startDate: reservation.startDate, endDate: reservation.endDate });
return true;
}
});
});
free = rooms.filter(function (a) {
return !booking[a];
});
console.log(free);
Results:
A210.3
A220.5
A320.2
A520.6
A510.4
This only returns the ones that are not being used at all during the day but I need to get the ones that are vacant for hour or two.
For this booked class for example:
"startDate": "2017-04-27T13:15:00",
"endDate": "2017-04-27T16:00:00",
"type": "room",
"code": "A520.5"
for this I would need to print out:
A520.5 - 2 hours 20 minutes
So I need to get the room / time from the startDate of the search (2017-04-27T10:55) and compare it to the startDate of the booked room (2017-04-27T13:15:00) to get the time remaining for that room to be vacant.
TO CLARIFY:
I have all the data for booked rooms starting from 2017-04-27T10:55
until 2017-04-27T22:00 as you can see from the JSON response above.
I need to somehow compare the startDate of the JSON query when the user
searches for the rooms (2017-04-27T10:55) and compare it to the booked
rooms startDate to get the time how long the room stays vacant.
This is how I'm doing my startDate and endDate for the JSON query:
// Timestamp needs to be formed (YYYY-MM-DDTxx:xx) in order for JSON query to work
var todaysDate = new Date();
function convertDate(date) {
var yyyy = date.getFullYear().toString();
var mm = (date.getMonth() + 1).toString();
var dd = date.getDate().toString();
var mmChars = mm.split('');
var ddChars = dd.split('');
return yyyy + '-' + (mmChars[1] ? mm : "0" + mmChars[0]) + '-' + (ddChars[1] ? dd : "0" + ddChars[0]);
}
// Current time when user searches for vacant rooms
var currentTime = new Date();
var time = "T" + currentTime.getHours() + ":" + currentTime.getMinutes();
// variables for the JSON query
var startDate = convertDate(todaysDate) + time;
var endDate = convertDate(todaysDate) + ("T22:00");
// JSON-query
var getRooms = {
"startDate": startDate,
"endDate": endDate
};

How to add anther "entry" into this JSON?

I downloaded some JSON, as shown below. In the developer console it looks like an object containing nested objects which contain nested objects ...
I would like to add a new, empty "campaign" into the data (at the front). How do I do that?

Work out what the next campaign id should be:
var nextId = +Object.keys(obj.campaigns).sort().pop() + 1;
Add the empty campaign to the campaigns object. Obviously you'll need to define date beforehand.
obj.campaigns[nextId] = {
'title': '',
'description': '',
'path_to_logo': '',
'start_time': date,
'end_time' : date,
'paused': false
}

Indexing last number of a JSON Object

So I have a JSON object, here it is:
{
"868": {
"header": "New limited",
"lite": "1337 Gaming Headset",
"icon": "",
"items": { "Stock": "1,337", "Price": "R$750" },
"extra": { "product": 25355494 },
"url": "",
"id": 868,
"added": 1438542256903
},
"869": {
"header": "New Face",
"lite": "Furious George",
"icon": "",
"items": { "Price": "R$200" },
"extra": { "product": 25355932 },
"url": "",
"id": 869,
"added": 1438543456863
},
"870": {
"header": "Almost sold out",
"lite": "1337 Gaming Headset",
"icon": "",
"items": { "Stock": "1,337", "Remaining": "133", "Price": "R$750" },
"extra": { "product": 25355494 },
"url": "",
"id": 870,
"added": 1438544588831
},
"871": {
"header": "Sold out",
"lite": "1337 Gaming Headset",
"icon": "",
"items": { "Price": "R$750" },
"extra": { },
"url": "",
"id": 871,
"added": 1438544704049
},
"872": {
"header": "New Hat",
"lite": "Elite Spy Eye",
"icon": "",
"items": { "Price": "R$250" },
"extra": { "product": 25356879 },
"url": "",
"id": 872,
"added": 1438545677167
}
}
I want to know how to index the last thing of this json object. I can't describe it any more but it might be the key.
I want to basically index the last object in the object, so that would be the bit where it says "872":{"header":"New Hat" near the bottom
So basically it's the biggest number I want to index. I already tried to index the last one with [4] as an index but it came up with undefined.
I suppose that you might want this:
var str = '{"868":{"header":"New limited","lite":"1337 Gaming Headset","icon":"","items":{"Stock":"1,337","Price":"R$750"},"extra":{"product":25355494},"url":"","id":868,"added":1438542256903},"869":{"header":"New Face","lite":"Furious George","icon":"","items":{"Price":"R$200"},"extra":{"product":25355932},"url":"","id":869,"added":1438543456863},"870":{"header":"Almost sold out","lite":"1337 Gaming Headset","icon":"","items":{"Stock":"1,337","Remaining":"133","Price":"R$750"},"extra":{"product":25355494},"url":"","id":870,"added":1438544588831},"871":{"header":"Sold out","lite":"1337 Gaming Headset","icon":"","items":{"Price":"R$750"},"extra":{},"url":"","id":871,"added":1438544704049},"872":{"header":"New Hat","lite":"Elite Spy Eye","icon":"","items":{"Price":"R$250"},"extra":{"product":25356879},"url":"","id":872,"added":1438545677167}}';
var obj = JSON.parse(str);
var last = Object.keys(obj).sort(function(a, b) {
return parseInt(b) - parseInt(a);
})[0]; // suppose to be "872" in this case
console.log('"' + last + '": ' + JSON.stringify(obj[last]));
var json = {
"868": {
"header": "New limited",
"lite": "1337 Gaming Headset",

"items": { "Stock": "1,337", "Price": "R$750" },

var keys = Object.keys(json);
