How to run javascript in windows 10?

Introduction

Running JavaScript in Windows 10 is a fundamental skill for web developers and enthusiasts alike. JavaScript is a versatile programming language that allows you to add interactivity and dynamic elements to your websites. In this article, we will explore different methods and tools to run JavaScript code on Windows 10, whether you are a beginner or an experienced developer.

Using a Web Browser

Step 1: Open your preferred web browser, such as Google Chrome, Microsoft Edge, or Mozilla Firefox.

Step 2: Create a new HTML file by right-clicking on your desktop or in a folder, selecting “New,” and then “Text Document.” Rename the file with a .html extension, for example, “script.html.”

Step 3: Open the HTML file in a text editor, such as Notepad or Visual Studio Code.

Step 4: Inside the HTML file, add the following code snippet between the <script> and </script> tags:


<script>
// Your JavaScript code goes here
</script>


Step 5: Write your JavaScript code within the <script> tags. For example, you can use the alert() function to display a message:


<script>
alert("Hello, Windows 10!");
</script>


Step 6: Save the HTML file and double-click on it to open it in your web browser. You should see a pop-up message with the text “Hello, Windows 10!”

Using a Code Editor

If you prefer a more comprehensive development environment, you can use a code editor specifically designed for web development. Some popular code editors include Visual Studio Code, Sublime Text, and Atom. These editors provide advanced features like syntax highlighting, code completion, and debugging capabilities.

Step 1: Install a code editor of your choice by downloading it from the official website and following the installation instructions.

Step 2: Open the code editor and create a new file by selecting “File” and then “New File” or using the keyboard shortcut.

Step 3: Write your JavaScript code directly in the code editor. For example:


alert("Hello, Windows 10!");


Step 4: Save the file with a .js extension, for example, “script.js.”

Step 5: Open your preferred web browser and create a new HTML file following the steps mentioned in the previous section.

Step 6: Link the JavaScript file to the HTML file by adding the following code snippet between the <script> and </script> tags:


<script src="script.js"></script>


Step 7: Save the HTML file and double-click on it to open it in your web browser. The JavaScript code from the linked file will be executed.

Using Node.js

Node.js is a runtime environment that allows you to run JavaScript code outside of a web browser. It provides a vast ecosystem of libraries and tools for server-side and command-line applications.

Step 1: Install Node.js by downloading the installer from the official website and following the installation instructions.

Step 2: Open a text editor and create a new file. For example, create a file named “script.js.”

Step 3: Write your JavaScript code in the file. For example:


console.log("Hello, Windows 10!");


Step 4: Save the file.

Step 5: Open the command prompt or terminal on your Windows 10 machine.

Step 6: Navigate to the directory where you saved the JavaScript file using the cd command. For example:


cd C:pathtofile


Step 7: Run the JavaScript file using the node command followed by the file name. For example:


node script.js


You should see the output “Hello, Windows 10!” in the command prompt or terminal.

Conclusion

Running JavaScript in Windows 10 is essential for web development and other applications. Whether you choose to run JavaScript in a web browser, a code editor, or using Node.js, the process is straightforward and accessible to both beginners and experienced developers. By following the steps outlined in this article, you can start running JavaScript code on your Windows 10 machine and explore the endless possibilities of this powerful programming language.
