JavaScript

The code doesn't respect the order of JavaScript like the video

This code does not show the correct order like the video in JavaScript Basics.

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>JavaScript Basics</title>
    <link href="css/style.css" rel="stylesheet">   
    <script>
      alert("Another message inside index.html")
    </script>
  </head>
  <body>
    <main>
      <h1>Hello, JavaScript!</h1> 
    </main>
    <script src="js/script.js"></script>
  </body>
</html>

The video shows first the first alert of Javascript inside <head>, then shows the <h1> element and finally the last JavaScript script.

But, when I execute my code in HTML first appears both alerts and finally the <h1> element.

Why does it happen?

Standard modern browser behavior is to run all scripts before rendering and displaying the page.
Older browsers (like when the video was made) behaved differently.

Thank you Steven!
