Replace Strings in a nested Object with values from another file using `string.replace() Method`

How can I replace the tokens __fruit_type__, __clothing_type__, __fitness_equipment__, __meditation_app__ in collection.js with values from values.js?

I am trying to achieve this with the string.replace() Method

   collection.js
{
  "collection" : [
    {
      "fruit": "__fruit_type__"
    "clothings":{
      "item": "__clothing_type__}"
    }
  }, 
  {
    "fitness": "__fitness_equipment__"
    "mindfulness": "app called __meditation_app__"
  }
]
}
values.js
{
    "clothing_type": "winter",
   "fruit_type": "apple",
   "fitness_equipment": "treadmill",
   "meditation_app": "calm"
}

replace.js

const fs = require("fs").promises;

async function dataReader(filePath, data) {
  const result = await fs.readFile(filePath);
  try {
    return JSON.parse(result);
  } catch (e) {
    console.error(e);
  }
}
//read values
async () => {
  const value = await dataReader("./values.json");
  const clothing_type = value.clothing_type;
  const fruit_type = value.fruit_type;
  const fitness_equipment = value.fitness_equipment;
  const meditation_app = value.meditation_app;

  //read collection.json
  const data = await jsonReader("./flow.json");

  //replace tokens in `collection.js` with `values.js`
};

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() ...
