JS Loads Before HTML

Hi, everobody! An issue with the loading of JS code I didn't change anything in HTML file. JS code stays before </body> Despite it alert(""); loads before <h1> and sometimes before the page at all

The HTML code actually loads first, but the browser doesn't render it to the screen until the JavaScript program runs and finishes. So it's normal for any "alert" messages in the js code to show before the page does.

This is normal operation, it doesn't require a "solution". When communicating from the program, you use "prompt" and "alert". When communicating through the web page, you use event handlers and DOM updates.

Techniques for using event handlers will be covered in later courses.
