File type node js

Use the following steps to create a basic Node.js file:

1. Open a text editor or integrated development environment (IDE) of your choice.

2. Create a new file with a .js extension, for example, "app.js".

3. Write your Node.js script inside the file using JavaScript syntax.

4. Save the file in your desired location on your computer.

5. To run the Node.js file, open a terminal or command prompt, navigate to the file's directory, and type "node app.js" (replacing "app.js" with your actual file name) to execute the script.

6. You should see the output of your Node.js script in the terminal/command prompt.

These are the basic steps for creating and running a Node.js file.
