JavaScript Program To Print Hello World

In this example, you will learn to print ‘Hello World’ in JavaScript in three different ways.

“Hello, World!” is a simple program that prints Hello, World! on the screen. Since it’s a very simple program, this program is often used to introduce a new programming language to beginners.

We will use these three ways to print 'Hello, World!'.

  • console.log()
  • alert()
  • document.write()

1. Using console.log()

console.log() is used in debugging the code.

Source Code

// the hello world program
console.log('Hello World');


Hello, World!

Here, the first line is a comment.

// the hello world program

The second line

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

prints the ‘Hello, World!’ string to the console.

2. Using alert()

The alert() method displays an alert box over the current window with the specified message.

Source Code

// the hello world program
alert("Hello, World!");

3. Using document.write()

document.write() is used when you want to print the content to the HTML document.
