Hello World: Writing Your First JavaScript Program
“Hello World” is a staple of programming courses. The objective of this program is simple: output the text “Hello World” on your computer screen. Because of the simplicity of the message and syntax, it is usually the first program taught to beginners.
Writing a “Hello World” program in JavaScript code, as we will learn, is exceptionally easy and requires not more than 3 lines of code.
What You’ll Need:
Since JavaScript is interpreted by the browser itself. We don’t need any fancy compilers / additional software to write JS programs. All you need is:
text editor: Notepad will do just fine, but we highly recommend Notepad++ (free).
web browser: You can use anything you want – Google Chrome, Firefox, Internet Explorer and Safari.
Getting Started: Creating the HTML Framework:
First, create a simple HTML file where we can include our JavaScript code.
Open your text editor and type the following code into it:
<!DOCTYPE HTML> <html> <head> <title>JavaScript Hello World</title> </head> <body> <h1>JavaScript Hello World Example</h1> </body> </html>
Save this file as test.html
OUTPUT:
