How to Rename File In Directory Using Javascript

Question

I am having JavaScript file under menu directory in the root menu.js. I want to rename JavaScript file menu.js to menuOLD.js under same directory onClick. I would have googled and found small sample as :

function renamefile(){
         const myFile = new File(['hello-world'], 'my-file.txt');
         const myRenamedFile = new File([myFile], 'my-file-final-1-really.txt');
         
         console.log(myRenamedFile);
          
     }

I have checked it's output in Console and got below output:

It's working.

But I would need to rename excatly menu.js file under menu directory. How should I do this?

Just for clarification, do you mean that issue is that the old file has to be exactly named menu.js or that the new file will be explicitly menuOLD.js? If possible, do explain your desired results again. — IcyBloom

@IcyBloom actual file is menu.js which has to be renamed as menuOLD.js. Renaming will perform if user performs onClick event. — Sumeet Kumar

I don't think it is possible to interact with the filesystem in a browser environment (I could be wrong though), but if you are using Node.js, then the fs module will let you do that. — Keldan Chapman

@KeldanChapman kindly show me small demo or reference if possible. — Sumeet Kumar

There is no way to save a file from browser in this way. You need to perform this on the server side. — Abrar Hossain

With Node.js

const fs = require('fs');

fs.rename('menu.js', 'menuOLD.js', (err) => { 
  console.log(err);
});
