Using 'var' instead of 'const'?

This exercise reports incorrect if I use const when declaring the weatherAPI url, isn't the rule to start with 'const' if the variable doesn't need to be changed?

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 course was released in 2014 so the validation mechanism probably doesn't accept ES2015 syntax.

You did good. Just simply delete the equal to and semicolon symbols. You need this var weatherAPI.

The "best practice" would be to keep the semicolon.

You're right, it works. I tried solved first task without equal to and semicolon.

Thank you, wasn't sure if it was just dated or if there was something AJAX/jQuery related that I was missing.
