Node.js Command Line Interface
To use the Node.js command line interface, follow these steps:
Open the command prompt: On Windows, open the command prompt utility. On macOS or Linux, open the terminal.
Navigate to the desired folder: Use the
cd
command to navigate to the folder where you want to work. For example, if you want to navigate to a folder named "my-project", you can use the following command:cd my-project
Create a JavaScript file: Use a text editor to create a JavaScript file with a
.js
extension. For example, you can create a file namedapp.js
.Write your JavaScript code: Open the JavaScript file in a text editor and write your Node.js code. You can use any text editor of your choice, such as Visual Studio Code, Sublime Text, or Atom.
Save the file: Save the JavaScript file with your code.
Run the JavaScript file: In the command prompt or terminal, use the
node
command followed by the name of the JavaScript file to run it. For example, if your file is namedapp.js
, you can use the following command:node app.js
The Node.js runtime will execute the JavaScript code in the file and display the output, if any.
That's it! You have successfully used the Node.js command line interface to run a JavaScript file.
Please note that the above steps assume you have Node.js installed on your system. If you haven't installed Node.js yet, you can download it from the official Node.js website and follow the installation instructions specific to your operating system.
