Hey there, friend!
Welcome to our JavaScript tutorial! Today, we're going to learn about Output Statements in JavaScript. You know, like how to print "Hello, world!" on the screen.
By now, you've already learned some basics of JavaScript, and you're ready to take the next step. So, let's get started!
Step 1: Open your index.js file
You should already have an index.js file open in your online IDE. If not, create a new file and name it index.js. This is where we'll write our code.
Step 2: Write the code
In your index.js file, write the following code:
console.log("Hello, world!")
What does this code do? It uses the console.log() function to print "Hello, world!" to the console. Think of it like a magic printer that outputs text to the screen.
Step 3: Run the code
Click the "Run" button to execute the code. This will run the code in the browser environment, and you'll see the output in the console.
Step 4: Check the console output
Look at the console output below your code editor. You should see "Hello, world!" printed out. Woohoo!
How it works
In JavaScript, console.log() is a function that outputs text to the console. It's like a print statement in other languages. When we pass a string like "Hello, world!" to console.log(), it prints that string to the console.
Real-world example
Imagine you're building a website that welcomes users with a personalized message. You could use console.log() to print out a greeting like "Hello, [username]!" to the console.
What's next?
Now that you've learned about Output Statements, you're ready to dive into Variables and Data Types. In the next tutorial, we'll explore how to store and manipulate data in JavaScript.
That's it for today, folks! You've taken your first step in mastering JavaScript Output Statements. Keep practicing, and soon you'll be building amazing things!
Run the code again to see the output, and then move on to the next tutorial to learn about Variables and Data Types. Happy coding!
