getting filehandler is not a constructor when using new filehandler but does not work as static class

When attempting to export a JavaScript module, it's best practice to specify a default or named exports to facilitate proper usage.

In your case, since you're not specifying a default export, importing the module using the FileHandler variable as a constructor will result in an error because it's not a constructor function. To resolve this:

• Option 1: Use named exports.

import * as filehandler from "../index.js";

const FileHandler = filehandler.FileHandlerStatic;

• Option 2: Use the as keyword when importing named exports.

import { FileHandlerStatic as FileHandler } from "../index.js";

Both approaches ensure proper usage of your exported module and avoid the "filehandler is not a constructor" error when using new filehandler.
