Steps for converting TypeScript code to JavaScript using jQuery, without the need for extra libraries or frameworks like NPM

My single-page dashboard is quite basic, as it just displays weather updates and subway alerts. I usually refresh it on my local machine, and the structure looked like this:

project/
  index.html
  jquery-3.3.1.min.js
  script.js

I decided to switch it to TypeScript. I converted `script.js` to TypeScript but needed to download jQuery's definition file from here. Now, my project directory looks like this:

project/
  index.html
  jquery.d.ts
  script.ts

The initial lines of my TypeScript file are:

/// <reference path ="./jquery.d.ts"/>
import * as $ from "jquery"

After running `tsc *.ts`, my script compiles successfully. However, the first few lines of the resulting JavaScript file are causing issues:

"use strict";
exports.__esModule = true;
/// <reference path ="./jquery.d.ts"/>
var $ = require("jquery");

This leads to an error in the browser stating:

exports.__esModule = true; // Can't find variable: exports

As someone who is not very experienced with front-end development beyond HTML/JS/jQuery, I'm a bit lost. I tried searching online for solutions but didn't find much useful information.

If you're looking to do this...

you can utilize declare var $: JQuery when the type is specified

otherwise, you can use declare vas $: any

if your editor (such as VSCode) supports script variable declarations, try using

{ 
 name: "$",
 type: JQuery (or any),
 ofReference: {
  scriptSrc: ["*jquery.js", "*jquery.min.js", "*code.jquery*"] 
 }
}
