Replace the contents in multiple JSON files based on their file name?

Question

How to replace the contents in multiple JSON files based on their file name? I have a certain number of description files and I need to sort their contents by file name. For ex. files numbered 1.json, 2.json, ... 10.json All files inside have the same object names, but different numbers

{
  "name": "Garlic 8",
  "position": 8,
  "description": "Only for stuff.",
  "external": "row five",
  "image": "buffer/8.png",
  "basic": [
    {
      "type": "row",
      "value": "one"
    },
    {
      "color": "pure",
      "value": "no"
    }
   ]
}

How to replace numbers in all files with numbers from file names? (i.e. the numbers inside the file must match the file number)

const basePath = process.cwd();
const fs = require("fs");

const {baseUri, namePrefix,} = require(`${basePath}/src/config.js`);

        

  for (
      let i = 1;
      i <= 10;
      i++
      )
  {
    let rawdata = fs.readFileSync(`${basePath}/rename/json/${i}.json`);
    let data = JSON.parse(rawdata);
    
    var originalMsg = JSON.stringify(data);

    
    data.each(function(item) {
      {
          item.name = `${namePrefix} #${i}`;
          item.position = `${i}`;
          item.image = `${baseUri}/${i}.png`;
      }
    });
    
    console.log(originalMsg)       
    console.log(data) 

But typeError: data.each is not a function
