How to get the most recently image in a folder? - node.js

Question

How can I get the most recent image that was added to a folder and save that image file path to a variable? I have checked on here (stack overflow) but don't see a post that specifically answers my questions. This is what I have so far it lists out all the files but I am unsure how to get them sorted by most recently modified. This is a unique and specific question. I don't mind if this code is used or not as long as the result is code that can get the most recent file in a folder.
Code:
(async () => {
var lastdownloadedimage = "";
var pathtocheck = "C:/Users/user1/Downloads";
var pathtocheckimage = "C:/Users/user1/Downloads/ot.png";
const testFolder = pathtocheck;
const fs = require('fs');
var lastdownloadedimage;
var filescount = 0;
var filename = [];
var filedates = [];
var filessortedbytimefromcurrentdateaccending = [];
var files;
//create a tuple for the file date and name
var filedata = [];
//fs.readdirSync(testFolder).forEach( filescount++);
files = fs.readdirSync(testFolder);
filescount = files.length;
console.log(files[0]);
filedates = fs.statSync(pathtocheckimage).mtime.getTime();
filename = fs.readdirSync(testFolder);
console.log(filescount);
for(var currentfiletocheck = 0; currentfiletocheck < filescount ; currentfiletocheck++){
//get current date
//find dile that is closest to current date
//use the index of that file data to find the file name
//save the files name to a variable
//filename[currentfiletocheck] = fs.readdirSync(testFolder)[currentfiletocheck];
//filedates[currentfiletocheck] = fs.stats.mtime.getTime()[currentfiletocheck];
//filedata[currentfiletocheck][0] = filename[currentfiletocheck];
//filedata[currentfiletocheck][1] = filedate[currentfiletocheck];
//console.log(files[currentfiletocheck]);
}
filessortedbytimefromcurrentdateaccending
filedata.sort(function(a, b) {
return a < b ? -1 : (a > b ? 1 : 0);
});
for (var i = 0; i < filedata.length; i++) {
var filenamessortedbytimefromcurrentdateaccending = filedata[i][0];
var filedatesortedbytimefromcurrentdateaccending = filedata[i][1];
lastdownloadedimage = filedatesortedbytimefromcurrentdateaccending;
// do something with key and value
}
/*
*/
console.log(lastdownloadedimage);
})();

I have taken a different approach, and rather than gather the timestamps and sort them, I iterate over the files and compare each timestamp with the next one - keeping the timestamp and file path of the later timestamp each time.
Note that this will also check directories, so you will have to implement a filter if you want to ignore them.
let fs = require('fs')
let dirToCheck = '.'
let files = fs.readdirSync(dirToCheck)
let latestPath = `${dirToCheck}/${files[0]}`
let latestTimeStamp = fs.statSync(latestPath).mtime.getTime()
files.forEach(file => {
let path = `${dirToCheck}/${file}`
let timeStamp = fs.statSync(path).mtime.getTime()
if (timeStamp > latestTimeStamp) {
latestTimeStamp = timeStamp
latestPath = path
}
});
console.log(latestPath)
