Node.js is a versatile tool for running JavaScript code outside of web browsers. It’s used widely to build server-side applications, command-line tools, and scalable network programs.
To get started with Node.js, follow these simple steps:
- Download the installer: Visit the official Node.js website (https://nodejs.org/) and click on the “Download” button to get the latest version of the Node.js installer.
- Run the installer: Double click the node js downloaded installer file and follow the on screen instructions to complete the installation process.
- Verify the installation: Once installed, open a terminal or command prompt and type the following command
node -vThis command will display the installed version of Node.js, confirming that the installation was successful.
That’s it! You now have Node.js installed on your system, allowing you to execute JavaScript code using the “node” command.
If you’re using Visual Studio Code (VS Code) to write and run JavaScript code, follow these additional steps:
- Install VS Code: If you don’t already have it, download and install VS Code from the official website (https://code.visualstudio.com/).
- Create a new JavaScript file: Open VS Code, create a new file with a .js extension, and save it.
- Write your JavaScript code: Enter your JavaScript code into the file.
- Run the JavaScript file: Open the Command Palette (Ctrl + Shift + P), type “Run JavaScript,” and select “Run JavaScript file in the terminal” from the options. This will execute your JavaScript code and display the output in the terminal window.
Alternatively, you can run JavaScript code directly in the terminal using Node.js. Install Node.js as described earlier, then use the “node” command followed by the name of your JavaScript file to execute it.
