How can I store mapping orders in BBDD and then eval them

I'm trying to store in MongoDB one document with an object with the properties I want to map latter. My idea it's to create a function that will receive 2 params. First the object where I got to find the mapping, and second the object where I have to take the info from.
For example I want to store this JSON (that would be the first parameter in the function):
{
"name": "client.firstName",
"surname": "client.surname",
"age": "client.age",
"skills": [
{
"skillName": "client.skills[index].name",
"level": "client.skills[index].levelNumber",
"categories": [
{
"categoryName": "client.skills[index].categories[index].name",
"isImportant": "client.skills[index].categories[index].important"
}
]
}
]
}
And the second paramenter would be something like this (it's the object where you find the information.
{
"client": {
"firstName": "Jake",
"surname": "Long",
"age": 20,
"skills": [
{
"name": "Fly",
"level": 102,
"categories": [
{
"name": "air",
"important": true
},
{
"name": "superpower",
"important": false
}
]
},
{
"name": "FastSpeed",
"level": 163,
"categories": [
{
"name": "superpower",
"important": false
}
]
}
]
}
}
The idea it's: with de paths that I have in the first object, find it in the second one.. The problem I found it's when I have arrays, because when I defined the mapping rules I don't know how many positions will have the array I want to map. So in the mapping object (first) I'll only define the path but I'll not put it with the same lenght of the secondone because I don't know how much it will have.

Merge a Product Config JSON with Generic Config JSON- Issue While Merging Arrays inside it

I have 2 different Json files
1: a Deaflut JSON file
2: A Product Based JSON file
I need to merge them together in such a way that if a feature in default is not in a product that needs to be added to product config from default one.
for this merge, I used "lodash.mergewith" https://www.npmjs.com/package/lodash.mergewith.
so this is now taking care of the merge, But the file contains multiple nested JSON arrays inside it.
to handle that there is an option to use a customizer method that can handle array merge as mentioned in the usage of lodash.mergewith. I need a customizer that can find the Label from Deaflut and compare it with the Product if the Product has the same Label value then replace the URL with the Product URL. else if the Label is not in Product config, then use it from default as it is.
Example
Default config.json:-links is an array of this json with path : object►login►options►sections►2►links
"links": [{
"url": "www.google.com",
"label": "Lable1"
},
{
"url": "www.google.com",
"label": "Label2"
},
{
"url": "www.google.com",
"label": "Label3"
},
{
"url": "www.google.com",
"label": "Label4"
}
]
Productconfig.json:- links is an array inside this of the path: object►login►options►sections►2►links
"links": [{
"url": "www.product1.com",
"label": "label1"
},
{
"url": "www.product2.com",
"label": "Label2"
}
]
** after merge mergedconfig.json "Links" need to be like this.**
"links": [{
"url": "www.product1.com",
"label": "Label1"
},
{
"url": "www.product2.com",
"label": "Label2"
},
{
"url": "www.google.com",
"label": "Label3"
},
{
"url": "www.google.com",
"label": "Label4"
}
]
The main concern is this Array is coming inside a JSON file inside some JSON objects
like eg if the Array is inside links[] it will be in a path like : object►login►options►sections►2►links[]. and this Links Array similarly present inside in some other paths eg: object►register►options►sections►2►links[]
So I need to figure out all the Array like this and for each of the Arrays, I need to perform this action.

Just use Array.map and Array.find:
let links= [
{
"url": "www.google.com",
"label": "Label1"
},
{
"url": "www.google.com",
"label": "Label2"
},
{
"url": "www.google.com",
"label": "Label3"
},
{
"url": "www.google.com",
"label": "Label4"
}
];
let plinks= [{
"url": "www.product1.com",
"label": "label1"
},
{
"url": "www.product2.com",
"label": "Label2"
}
];
let results = links.map(lnk=>{
plnk = plinks.find(pl=>pl.label.toLowerCase()===lnk.label.toLowerCase());
return plnk || lnk
});
console.log(results);
for clean access to nested JSON keys you can use ES like this:
let a = {
b: {
c: [1,2,3]
}
};
let {c} = a?.b;
console.log(c);

Extract information from json

So I have the following object from my controller, which has a name, a list of beans and a list of operations:
{
"name": "Charge",
"beans": [
],
"operations": [
{
"name": "getSize",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
]
},
{
"name": "truncate",
"returnType": "java.lang.Void",
"description": "empty description",
"parameters": [
]
},
{
"name": "count",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "update",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaSelectCode",
"type": "java.lang.String",
"value": null
},
{
"name": "javaUpdateCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "delete",
"returnType": "java.lang.Integer",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "dump",
"returnType": "java.lang.Void",
"description": "empty description",
"parameters": [
{
"name": "javaSelectCode",
"type": "java.lang.String",
"value": null
},
{
"name": "destinationPath",
"type": "java.lang.String",
"value": null
}
]
},
{
"name": "select",
"returnType": "java.lang.String",
"description": "empty description",
"parameters": [
{
"name": "javaCode",
"type": "java.lang.String",
"value": null
}
]
}
],
"$$hashKey": "object:620"
}
Basically I want to display all the operations from this object in a dropdown menu.
So I was thinking of having something like:
<div ng-repeat="operation in object.operations">
{{operation.name}}
</div>
Except the code above doesn't display anything on the screen, no errors in the console, nothing.
Any help would be much appreciated!
EDIT:
Javascript service:
app.controller('selectAll', ['$http', '$scope' , '$rootScope', function ($http, $scope, $rootScope) {
$scope.response;
$scope.operations;
$rootScope.$on("invokeSelectAll", function(){
$scope.invokeSelectAll();
});
$scope.invokeSelectAll = function(){
$scope.response = $http.post('/invoke/selectAll/', $rootScope.dataObj);
$scope.object = JSON.stringify($rootScope.object);
console.log(" object operation from selectAll " + $scope.object);
$scope.response.then(function(data) {
$scope.responses = data.data ? data.data : "Select Operation not supported on this bean";
});
}
}]);

Use JSON.stringify() to create a JSON string from a JavaScript object.
Use JSON.parse() to parse a JSON string to a JavaScript object.
In your case, you need to use JSON.parse() because you get a JSON string from the server and want to parse it to a JavaScript object.
$scope.object = JSON.parse($rootScope.object);

you are using JSON.stringify which is used to change javascript object to string and store it as a string only.
You should Parse the data with JSON.parse(), and the data becomes a JavaScript object. and you can easily use that in ng-repeat.
Try it ,It will work fine

Using jq to assign property of child to parent dictionary

I have a TopoJSON file with several geometries. It looks like so:
{
"type": "Topology",
"objects": {
"delegaciones": {
"geometries": [
{
"properties": {
"name": "Tlalpan",
"municip": "012",
"id": "09012",
"state": "09"
}
...
I want to be able to take the id field from properties, and assign it to the parent, so that the result is:
{
"type": "Topology",
"objects": {
"delegaciones": {
"geometries": [
{
"id": "09012",
"properties": {
"name": "Tlalpan",
"municip": "012",
"id": "09012", // <-- It's okay if it's removed or not
"state": "09"
}
...
I tried the following assignment on jq, but it's not correct:
jq '.objects.delegaciones.geometries[].id = .objects.delegaciones.geometries[].properties.id' topo_df.json
Anyone know how I can make jq iterate elements one by one? Or how I can make this work?

The following adds the "id" property as requested:
.objects.delegaciones.geometries[] |= (.id = .properties.id)

Iterate through nested Javascript Objects from API response

I've tried 100 different things, and spend days looking through Google and Stackoverflow, but I can't find a solution to this problem. Everything I call after the body of this API response returns undefined!
The response from Facebook SDK looks like this:
[
{
"body": "[
"data": [

"administrator": false,
"id": "xxx"
}, {
"name": "Charlotte Masson",
"administrator": false,
"id": "xxx"
}
],
"paging": {
"next": "url"
}
]"
},{
"body": "{
"data": [
{
"id": "xxx_xxx",

This response is from a batch call. If I call them separately, I can easily iterate through the responses, and get everything from them. When I call them in the batch though, I can't get past "body", and I need to use a batch call.
console.log(response[0].body); will return the object inside the body of the first part of the response, but console.log(response[0].body.data); returns undefined. I just don't get it. This should be simple but it's like there's a lock on the door and I don't have the right key.
I normally have no issue iterating through objects, so I don't need a generalized answer. I need help seeing whatever it is here that I don't see. Why does the console show undefined when I call anything after the body, and what do I need to be doing to get any of these values?

That JSON contains nested JSON. body seems to be a string. Use
var body = JSON.parse(response[0].body);

The values from the body are just strings.which are embedded as json.So firstly you would need to parse them using JSON.parse.
The code would be like
var body = JSON.parse(response[0].body);
