问如何使用nodejs在javascript中从一个文件调用函数到另一个文件？

EN

const image=require('./image');
const request=require('request');
const axios = require("axios");
const cheerio = require("cheerio");
const fs = require("fs");
const url = "https://www.google.com";
axios.get(url).then((res) => {
  const $ = cheerio.load(res.data);
const pageTitle = $("title").text();

const imageFile=image.imageNames();
console.log(imageFile)
const contentJSON = {
    title: pageTitle.trim(),
    url:url.trim(),
    listImages:listImages
  };
const artFinal = JSON.stringify(contentJSON);
  const filename = pageTitle.slice(0, 9).trim() + ".json";
  fs.writeFileSync(filename, artFinal);
});

const request=require('request');
const axios = require("axios");
const cheerio = require("cheerio");
const url = "https://www.google.com";
axios.get(url).then((res) => {
 const $ = cheerio.load(res.data);
function  imageNames(){
    var listImages=[];
    $('*').find('img').each(function (index, element) {
      var img={
        name: $(element).attr('href'),
        dom_data:$(element).attr(''),
      };
      listImages.push(img)
    });
}
module.exports={imageNames};
});
