First Code in Javascript - Learn & Explore

console.log("Hello, World!");

To run this program, you will need to have a web browser that supports JavaScript.

Open a text editor and copy the code above into a new file.
Save the file with a .js extension, for example main.js.
Create an HTML file that includes the JavaScript file you just created. You can do this by adding a <script> element to the HTML file and setting the src attribute to the path of the JavaScript file, like this:

<!DOCTYPE html>
<html>
  <head>
    <title>My JavaScript Program</title>
  </head>
  <body>
    <script src="main.js"></script>
  </body>
</html>

You should see the text “Hello, World!” printed to the console.
