How to write to a multidimensional array/object at an address in JavaScript?

Question

JavaScript

Greetings. Here I do not understand how to write data to a multidimensional array with objects at the address. For example, there is an array, an address (by the key property) and new data

var data = [
  {key:'raz', cells:[{val: '1'},{val:'razoviy'}]},
  {key:'dva', cells:[{val: '2'},{val:'vtoroy'}],children:[
    {key:'poddva', cells:[{val: '2'},{val:'podvtoroy'}],children:
    		[{key:'podpoddva', cells:[{val: '2'},{val:'podpodvtoroy'}]},{key:'raz', cells:[{val: '1'},{val:'raz'}]}]
    	},
      {key:'poddvadva', cells:[{val: '2'},{val:'podvtoroyvtoroy'}]}
  ]},
  {key:'tri', cells:[{val: '3'},{val:'trtiy'}]}
]

var adres = ['dva','poddva','raz']

var newDataCells = [{val: '1.0'},{val:'raz raz, est svyaz'}]

I don’t know how to build a script that would write data to this variable at the address. Well, just add new child objects ...

Answer 1

Solved the problem like this:

var data = [
  {key:'raz', cells:[{val: '1'},{val:'razoviy'}]},
  {key:'dva', cells:[{val: '2'},{val:'vtoroy'}],children:[
    {key:'poddva', cells:[{val: '2'},{val:'podvtoroy'}],children:
    		[{key:'podpoddva', cells:[{val: '2'},{val:'podpodvtoroy'}]},{key:'raz', cells:[{val: '1'},{val:'raz'}]}]
    	},
      {key:'poddvadva', cells:[{val: '2'},{val:'podvtoroyvtoroy'}]}
  ]},
  {key:'tri', cells:[{val: '3'},{val:'trtiy'}]}
]

var adres = ['dva','poddva','raz']
var newDataCells = [{val: '1.0'},{val:'raz raz, est svyaz'}]
var lastMath
Object.traverse(data, function(node, value, key, path, depth) {
    if(typeof value == 'object' && value.key){
    let indexAdres = 0;
    if(depth > 0)
      indexAdres = depth/2
    
    if(value.key == adres[indexAdres])
      lastMath = value
    }
});
lastMath.cells = newDataCells

console.log(data)

The Object.traverse method was taken from this post https://javascript.ru/forum/project/51879-object-t...

Answer 2

data[0].key= 1;
data[1].key= 2;

Answer 3

var data = [
  {key:'raz', cells:[{val: '1'},{val:'razoviy'}]},
  {key:'dva', cells:[{val: '2'},{val:'vtoroy'}],children:[
    {key:'poddva', cells:[{val: '2'},{val:'podvtoroy'}],children:
    		[{key:'podpoddva', cells:[{val: '2'},{val:'podpodvtoroy'}]},{key:'raz', cells:[{val: '1'},{val:'raz'}]}]
    	},
      {key:'poddvadva', cells:[{val: '2'},{val:'podvtoroyvtoroy'}]}
  ]},
  {key:'tri', cells:[{val: '3'},{val:'trtiy'}]}
]

var newDataCells = [{val: '1.0'},{val:'raz raz, est svyaz'}]

var obj = data.find(val => val.key == 'dva')
obj.cells = newDataCells;

console.log(data);
