How to correctly use JSON.parse()? JSON result is not valid

When I use JSON.parse(myJSONString) the result is not a valid JSON file. I'm in an nodejs environment. Any Ideas what I can fix in my code? I user XML2JS to converte an XML Api call to JS.
I have printed out the results and already dived deeper into JSON.parse but didn't find further information...
exports.getStations = functions.https.onCall(async (data) => {
let stations
await axios.get(encodeURI(`XMLAPi`))
.then(async (response) => {
parseString(response.data, (err, result) => {
stations = JSON.stringify(result)
console.log(stations) //First console.log
})
})
.catch((error) => {
console.log(error)
})
console.log(JSON.parse(stations)) //Second console.log
return JSON.parse(stations)
})
Result for first console.log (valid JSON but String):

You are already converting to string as a parsestring function. But it's also converting to JSON.stringify().
You can try check this value
let stations = await axios.get(encodeURI(`XMLAPi`));
console.log(JSON.stringify(stations.data)) // What is value??

Normalising JSON data

{
"id": "123",
"author": {
"id": "1",
"name": "Paul"
},
"title": "My awesome blog post",
"comments": [
{
"id": "324",
"commenter": {
"id": "2",
"name": "Nicole"
}
}
]
}
This is JSON for an article
{
result: "123",
entities: {
"articles": {
"123": {
id: "123",
author: "1",
title: "My awesome blog post",
comments: [ "324" ]
}
},
"users": {
"1": { "id": "1", "name": "Paul" },
"2": { "id": "2", "name": "Nicole" }
},
"comments": {
"324": { id: "324", "commenter": "2" }
}
}
}
Im currently looking through redux tutorials, they give a helper which normalise JSON data, does anyone know what type of normalisation this is?

Changing arrays using map in javascript

This is my json object:
{
"id": 2,
"service": "mobile",
"min": "20",
"per": "10",
"tax": "1",
"categoryservices": [
{
"category": {
"id": 1,
"name": "laptop"
}
},
{
"category": {
"id": 2,
"name": "software"
}
}
]
}
I want my output like this:
{
"id": 2,
"service": "mobile",
"min": "20",
"per": "10",
"tax": "1",
"cats": [1,2] // this 1 and 2 is coming from categoriesservices array inside the category object i have id
}
How to do this using map function? I am new to javascript, which is good approach map or forloop?

See destructuring assignment, Array.prototype.map(), and JSON for more info.
// Input.
const input = {
"id": 2,
"service": "mobile",
"min": "20",
"per": "10",
"tax": "1",
"categoryservices": [
{
"category": {
"id": 1,
"name": "laptop"
}
},
{
"category": {
"id": 2,
"name": "software"
}
}
]
}
// Categories => Objects to Cats => Ids.
const output = (input) => JSON.parse(JSON.stringify({
...input,
cats: input.categoryservices.map(({category: {id}}) => id),
categoryservices: undefined
}))
// Log.
console.log(output(input))

If you are not worried about original object immutability, then try this
obj['cats'] = obj['categoryservices'].map(cat => cat.category.id);
delete obj['categoryservices'];
console.log(obj);

I just use .map() on categoryservices array:
var output = {
"id": 2,
"service": "mobile",
"min": "20",
"per": "10",
"tax": "1",
"categoryservices": [
{
"category": {
"id": 1,
"name": "laptop"
}
},
{
"category": {
"id": 2,
"name": "software"
}
}
]
};
output.cats = output.categoryservices.map((element) =>
element.category.id);
delete output.categoryservices;
console.log(JSON.stringify(output));

use .map() , it return value as array ! You want to change is categoryservices key only ! So delete that after you get wanted value ..
var output = {
"id": 2,
"service": "mobile",
"min": "20",
"per": "10",
"tax": "1",
"categoryservices": [
{
"category": {
"id": 1,
"name": "laptop"
}
},
{
"category": {
"id": 2,
"name": "software"
}
}
]
};
output.cats = output.categoryservices.map(i => i.category.id );
delete output.categoryservices;
console.log(output);

Try this working demo :
var jsonObj = {
"id": 2,
"service": "mobile",
"min": "20",
"per": "10",
"tax": "1",
"categoryservices": [
{
"category": {
"id": 1,
"name": "laptop"
}
},
{
"category": {
"id": 2,
"name": "software"
}
}
]
};
var arr = jsonObj.categoryservices.map(item => item.category.id)
jsonObj.cats = arr;
delete jsonObj.categoryservices;
console.log(jsonObj);

Try this
var testData={
"id": 2,
"service": "mobile",
"min": "20",
"per": "10",
"tax": "1",
"categoryservices": [
{
"category": {
"id": 1,
"name": "laptop"
}
},
{
"category": {
"id": 2,
"name": "software"
}
}
]
}
testData.cats=[];
testData.categoryservices.forEach(function (item) {
testData.cats.push(item.category.id);
});
delete testData.categoryservices;
console.log(testData);

You can try using jquery each:
<div id="log"></div>
var conversation = {
'John': {
1: 'Test message 1',
2: 'Test message 2',
'Reply': {
3: 'Test message 3',
4: 'Test message 4'
}
},
'Jack': {
5: 'Test message 5',
6: 'Test message 6'
}
};
function iterate(obj) {
if (typeof obj === 'string') {
$('#log').append((obj + '<br/>'));
}
if (typeof obj === 'object') {
$.each(obj, function(key, value) {
iterate(value);
});
}
}
iterate(conversation);

lodash create new json object from existing one

I want to delete and rename some props of my existing JSON Object to use it with select2/select2 query plugins
My JSON object that i need to transform is:
[
{
"id": 1,
"type": "Subject1",
"createdAt": "2016-02-19T23:03:12.000Z",
"updatedAt": "2016-02-19T23:03:12.000Z",
"Tags": [
{
"id": 1,
"name": "sub1",
"createdAt": "2016-02-19T23:03:12.000Z",
"updatedAt": "2016-02-19T23:03:12.000Z",
"tagType": 1
}
]
},
{
"id": 2,
"type": "Subject2",
"createdAt": "2016-02-19T23:03:12.000Z",
"updatedAt": "2016-02-19T23:03:12.000Z",
"Tags": [
{
"id": 16,
"name": "sub2",
"createdAt": "2016-02-19T23:03:12.000Z",
"updatedAt": "2016-02-19T23:03:12.000Z",
"tagType": 2
}
]
},
{
"id": 3,
"type": "Subject3",
"createdAt": "2016-02-19T23:03:12.000Z",
"updatedAt": "2016-02-19T23:03:12.000Z",
"Tags": [
{
"id": 22,
"name": "sub3",
"createdAt": "2016-02-19T23:03:12.000Z",
"updatedAt": "2016-02-19T23:03:12.000Z",
"tagType": 3
}
]
}
]
To
[
{
"text": "Subject1",
"children": [
{
"id": 1,
"text": "sub1"
}
]
},
{
"text": "Subject2",
"children": [
{
"id": 16,
"text": "sub2"
}
]
},
{
"text": "Subject3",
"children": [
{
"id": 22,
"text": "sub3"
}
]
}
]
I need to :
rename name and type to text
delete tagType, updatedAt and createdAt
rename Tags to children
remove the id of each top objects
Is there a way to do all this using lodash ?
What the best way?

var res = _.map(items, function(item){
return {
text: item.type,
children: _.map(item.Tags, function(tag){
return {
id: tag.id,
text: tag.name
};
})
};
});

I succed using this link by nesting two return :
Creating new javascript Object form existing one
var result = tags.map(function(obj) {
return {
text: obj.type,
childrens:obj.Tags.map(function(obj) {
return {
id : obj.id,
text : obj.name
}
})
};
});
