How to Run JavaScript in Windows 10: A Step-by-Step Guide for Beginners

Running JavaScript in Windows 10 is straightforward. Whether you’re an aspiring coder or just curious, you can easily get JavaScript running using a text editor and your web browser. This article will guide you through the necessary steps, ensuring you can execute JavaScript code efficiently.

How to Run JavaScript in Windows 10

In the following steps, you’ll learn how to write and run a simple JavaScript program using just Notepad and a web browser. This process involves creating a basic HTML file with embedded JavaScript. Let’s get started!

Step 1: Open Notepad

Open Notepad by clicking the Start menu, typing "Notepad," and pressing Enter.

Notepad is a simple text editor included with Windows. It’s perfect for writing and editing JavaScript code because it doesn’t add any formatting, which can interfere with code execution.

Step 2: Write Basic HTML

In Notepad, start by writing a basic HTML template. Type:

    My First JavaScript

This HTML template sets up a simple web page. The “ tags are where you will write your JavaScript code.

Step 3: Add JavaScript Code

Inside the “ tags, add the following JavaScript code:

document.write("Hello, World!");

This JavaScript code will display "Hello, World!" on your webpage when it’s loaded.

Step 4: Save the File

Save the file with a .html extension. Click "File" > "Save As," then name your file something like myFirstJavaScript.html. Make sure to change the "Save as type" to "All Files."

Saving the file with an .html extension allows it to be recognized as an HTML document, which you can open in a web browser.

Step 5: Open the HTML File in a Browser

Double-click the saved .html file to open it in your default web browser.

This will load the HTML file in your browser, and you’ll see the text "Hello, World!" displayed, which confirms your JavaScript code is running.

Once you’ve completed these steps, you’ll see "Hello, World!" on your browser screen. This means your JavaScript code has successfully executed. You can now modify the JavaScript code inside the “ tags to perform different actions or display other messages.

Tips for Running JavaScript in Windows 10

• Keep your file organized by creating a dedicated folder for your projects.
• Use comments (//) in your JavaScript code to explain what each part does; this helps with debugging and collaboration.
• Experiment with different JavaScript functions like alert(), console.log(), and prompt() to see various outputs.
• If your code isn’t working, check for typos or missing characters in both your HTML and JavaScript.
• Use online resources like MDN Web Docs or W3Schools to learn more about JavaScript functions and best practices.
