JavaScript Hausa #3: Running JavaScript Code!
Welcome to the third lesson in our JavaScript series. Today, we'll talk about how to run JavaScript code. This is an exciting step because it means you'll see your code come to life! Let's get started.
What Does It Mean to Run JavaScript Code?
When you write JavaScript, it's just a set of instructions for the computer. To see what those instructions do, you need to "run" the code. Running JavaScript means letting the browser or another program execute your code and show the results.
There are several ways to run JavaScript, and we'll cover the most common ones here:
- Using the Browser Console: Every modern web browser has a built-in tool called the console where you can test small pieces of JavaScript code.
- Creating an HTML File: You can also write JavaScript inside an HTML file and open it in your browser to see the results.
- Using Node.js: If you want to run JavaScript outside of a browser (for example, on your computer), you can use Node.js.
How to Run JavaScript in the Browser Console
The easiest way to start running JavaScript is by using the browser console. Here's how you can do it:
- Open any web browser (like Google Chrome, Firefox, or Edge).
- Right-click anywhere on the page and select "Inspect" or "Inspect Element." This will open the Developer Tools.
- Click on the "Console" tab.
- Type some JavaScript code, like
console.log("Salamu alaikum!");, and press Enter. You should see the message printed in the console.
Congratulations! You've just run your first piece of JavaScript code.
How to Run JavaScript in an HTML File
If you want to create a full webpage with JavaScript, you can include your code inside an HTML file. Here's how:
- Open your text editor (like Visual Studio Code) and create a new file.
- Write the following code:
My First JavaScript Program
alert("Salamu alaikum!");
- Save the file with a .html extension, for example, "myfirstprogram.html".
- Open the file in your browser, and you should see an alert box with the message "Salamu alaikum!"
This is a simple example, but it shows how JavaScript can interact with web pages.

Final Thoughts
You've now learned two easy ways to run JavaScript code: using the browser console and creating an HTML file. These methods are perfect for beginners who want to experiment with JavaScript without any extra setup.
In the next lesson, we'll dive deeper into writing actual JavaScript programs. Keep practicing, and don't forget to have fun while learning!
Thank you for reading, and happy coding!
