How to Run a hello.js File in Node.js on Windows? 🚀💻

Are you new to Node.js and wondering how to run a hello world program written in JavaScript in a separate file named hello.js on a Windows environment? Don't worry, we've got you covered! In this guide, we'll address common issues and provide easy solutions to help you get your program up and running smoothly. Let's dive in! 💪

Common Issues and Solutions 🤔💡

Issue: Referencing the Path in a Windows Environment 📂✨

When running a hello.js file in Node.js on Windows, you might encounter difficulty referencing the path in the Windows environment. Let's explore the solutions:

1. Option 1: Use the "node" command followed by the absolute path to the hello.js file:

> node C:\abc\zyx\hello.js

1. Option 2: Add the node.exe executable to the folder where the hello.js file is located, and then run the command:

> cd C:\abc\zyx
> node hello.js

1. Option 3: Add the path to the folder (c:\abc\zyx\) containing the hello.js file to the system's environment variables. Once done, you can run the following command from any location:

> node hello.js

Issue: "ReferenceError: hello is not defined" ❌

If you receive this error message, it means that the "hello" variable is not declared or defined in the hello.js file. Let's take a look at the contents of the hello.js file provided:

setTimeout(function() {
    console.log('World!');
}, 2000);
console.log('Hello');

As you can see, the "hello" variable is not mentioned in the code. To resolve this issue, you can simply remove the "hello" variable from the code, as it is not being used.

Resolving the Issues and Running the hello.js File ✔️🏃‍♂️

Now that we have addressed the common issues, let's run the hello.js file successfully on Windows:

1. Make sure that the hello.js file and the node.exe executable are in the same folder.

2. Open the command prompt and navigate to the folder where the hello.js file is located:

> cd C:\abc\zyx

1. Run the following command:

> node hello.js

Congratulations! 🎉 The hello.js file will now be executed, and you should see the following output:

Hello
World! (after 2 seconds)
