A “Hello, World!” program is a simple computer program that outputs or displays the message “Hello, World!” on a screen or console. It is often used to introduce beginners to a new programming language or environment, as it demonstrates how to create a simple program and display output.

Here is an example of a “Hello, World!” program in JavaScript:

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

This code will print the message “Hello, World!” to the console when you run it. The console.log function is used to print output to the console in JavaScript.

The “Hello, World!” program is a simple way to make sure that the basic tools and setup needed to write and run a program are working correctly. It is also a way to verify that a programming environment has been properly installed and configured.
