Hello, World! with javascript

by Coders —

Prerequisite

  • Simple text editor ( We like Sublime )
  • Browser

Create a file helloworld.html (you can call it anything)

$ touch helloworld.html

Copy following content into your helloworld.html

<!DOCTYPE html>
<html>
<head>
    <title>Hello, World!</title>
</head>
<body>
</body>
</html>

If you open this file in the browser, you would not see anything! Don’t worry, we’ll make it say ‘Hello, World!’ in couple of minutes.

Now open your html file with a text editor and add following code inside <body> tag

<script>
    alert('Hello, World!');
</script>

Your file should look as below:

<!DOCTYPE html>
<html>
<head>
    <title>Hello, World!</title>
</head>
<body>
    <script>
        alert('Hello, World!');
    </script>
</body>
</html>

Now just refresh the page in the browser and Voila you should see ‘Hello, World!’ as below:
