Changing status of parent/children on the basis of boolean value

I have a array as follows:

[
  {
    data: {
      name: "Cloud",
      size: "20mb",
      type: "Folder",
      DisplayStatus: 1,
    },
    children: [
      {
        data: {
          id: 1,
          name: "backup-1.zip",
          size: "10mb",
          type: "Zip",
          isDisplayStatus: 1,
        },
      },
      {
        data: {
          id: 2,
          name: "backup-2.zip",
          size: "10mb",
          type: "Zip",
          isDisplayStatus: 1,
        },
      },
    ],
  },
  {
    data: {
      name: "Desktop",
      size: "150kb",
      type: "Folder",
      DisplayStatus: 0,
    },
    children: [
      {
        data: {
          id: 3,
          name: "note-meeting.txt",
          size: "50kb",
          type: "Text",
          isDisplayStatus: 0,
        },
      },
      {
        data: {
          id: 4,
          name: "note-todo.txt",
          size: "100kb",
          type: "Text",
          isDisplayStatus: 1,
        },
      },
    ],
  },
];

I have a method in which I will receive two arguments. One is boolean value and one is id.

  1. If boolean value is false, then I need to find the element in the array for the id which is coming as argument of method and set "isDisplayStatus" field to 0.

  2. If boolean value is true, then I need to find the element in the array for the id which is coming as argument of method and set "isDisplayStatus" field to 1.

  3. If for any children "isDisplayStatus" is 0, then "DisplayStatus" in parent should be set as 0. If all chilren "isDisplayStatus" is 0, then for parent "DisplayStatus" should be 0. If all children "isDisplayStatus" is 1, then for parent "DisplayStatus" should be 1.

My Try:

myMethod(flag, data) {
  if (flag == true) {
    this.isDisplayStatus = 1;
  } else if (flag == false) {
    this.isDisplayStatus = 0;
  }
  this.myArray = this.myArray.reduce(
    (f, i) => [
      ...f,
      {
        ...i,
        children: i.children.map((child) => ({
          ...child,
          data: {
            ...child.data,
            ...(child.data.id === data.id
              ? {
                  isDisplayStatus: this.isDisplayStatus,
                }
              : {}),
          },
        })),
      },
    ],
    []
  );
}

I am able to achieve 1 & 2 point but I am not able to achieve point 3. Please help

How can I do this?

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
