Get Ready to Code: Your First JavaScript Program
Welcome to the World of JavaScript
In our previous tutorial, we set up JavaScript on your computer. Now, it’s time to create something amazing! Let’s start with a classic: a “Hello, World!” program. This simple yet powerful program will introduce you to the basic syntax of JavaScript and get you excited for what’s to come.
The “Hello, World!” Program
Take a look at the code below:
console.log("Hello, World!");
What’s Happening Behind the Scenes?
When you run this program, you’ll see “Hello, World!” displayed on your screen. But how does it work? In JavaScript, console.log() is a function that prints output to the console. There are two key things to keep in mind:
- Anything you want to display goes inside the parentheses
(). - The text you want to print is wrapped in double quotes
" ".
Flexibility with Quotes
Did you know you can also use single quotes ' ' to print text in the console? For example, console.log('Hello, World!'); is equivalent to console.log("Hello, World!");. To maintain consistency throughout our tutorials, we’ll stick to double quotes.
