Won't let you use "const" or "let"

FYI: even though ES6+ allows the use of let and const, this challenge requires the use of var.

weather.js
$(document).ready(function() {
    var weatherAPI;
});
index.html
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>What's the Weather Like?</title>
  <script src="jquery.js"></script>
  <script src="weather.js"></script>
</head>
<body>
  <div id="main">
    <h1>Current temperature: <span id="temperature"></span>&deg;</h1>
  </div>
</body>
</html>

This is more of an community announcement, rather than a question.

That particular course was created before the ES6 syntax was commonly adopted.

Yes, this is true, but they have these lessons mixed with various ES6 lessons (Fetch API, Promises, etc.). So in case someone is coming here and wanting to use modern methods, I wanted to give a heads up.
