Answer 1

As I learned years ago you cannot access local file system with JS from browser, but things change. You can find more info here:

Local file access with javascript

The article directs you to MDN but the solution works only in certain browsers:

Answer 2

You can't access local files in modern web browsers. There is the HTML5 File API, but that involves direct user actions, you can't just use whatever files you please.

Answer 3

There is no way you cant access files using your browser , JavaScript is a view language its interact only with the browser, to be able to access local file you need to use a back end platform such as NodeJs or Php

Answer 4

This wont work because your browser does not have access to your file system.

you can run this from a node.js server
