Downloading Node.js
The first step to installing Node.js is to download the appropriate version for your operating system.
To do this, simply head over to the Node.js website and click on the big green Download button. From there, you will be given the option to select either the LTS or Current version.
The LTS version (Long-Term Support) is recommended for most users, as it provides a stable and reliable platform for development.
Choosing the appropriate release
Once you have selected either the LTS or Current version, you will need to choose the appropriate release for your operating system. You can choose from a variety of releases, including Windows, macOS, Linux, and ARM64.
Make sure to select the release that corresponds with your operating system to avoid any installation errors. Installing Node.js on Windows
If you are installing Node.js on Windows, you will need to use the official Node.js installer.
Simply download the installer from the Node.js website, open the file, and follow the instructions on the setup wizard. The wizard will guide you through the installation process, allowing you to select the appropriate installation folder and any additional features you may need.
Post-installation confirmation
Once you have installed Node.js, you will need to confirm that it was installed properly. To do this, open up the Command Prompt and type in node -v.
This will display the version number of Node.js you have installed. If the version number appears, then you have successfully installed Node.js!
Node.js Setup Wizard
Once you have downloaded Node.js, you will need to run the Node.js Setup Wizard to install the platform onto your computer.
Here are the steps you will need to follow to complete the setup process:
Computing space requirements
The first step of the Node.js Setup Wizard is to compute the space requirements for installing Node.js. This process takes only a few seconds and will give you an idea of how much space you will need to allocate for Node.js on your computer.
Accepting the license agreement
Next, you will be asked to review and accept the Node.js license agreement. Make sure to read through this agreement carefully, as it outlines the terms and conditions of using Node.js.
Selecting installation folder
After you have accepted the Node.js license agreement, you will need to select the installation folder for Node.js. You can choose any location on your computer that has enough space for Node.js, but the default location should work just fine for most users.
Choosing features to install
Once you have selected the installation folder for Node.js, you will need to choose the features you would like to install. By default, all features will be checked, but you can deselect any features that you do not need.
This will save space on your computer and speed up the installation process.
Installing necessary tools
Before Node.js can be installed on your computer, certain necessary tools must be installed first. This includes Chocolatey, a package manager for Windows.
The Node.js Setup Wizard will automatically download and install this tool for you.
Initiating installation
Once all necessary tools have been installed, the Node.js Setup Wizard will initiate the installation process. This may take a few minutes, depending on the size of your installation.
Completing installation
Once the installation process is complete, you will be given the option to launch Node.js. Make sure to select this option to confirm that Node.js was installed successfully.
You can also check the version number of Node.js in the Command Prompt, as we discussed earlier.
Conclusion
By following the steps outlined in this guide, you will be able to install Node.js on your computer with ease. Whether you are an experienced developer or just getting started, Node.js can help take your coding to the next level.

Node.js Interactive Environment: Getting Started
One of the best things about Node.js is its interactive mode, known as REPL (Read-Eval-Print Loop).
If you are just getting started with Node.js or want to test some code quickly, the interactive mode is a great place to start. In this guide, we will walk you through everything you need to know about using Node.js interactive environment.
Launching REPL
To launch Node.js interactive mode, simply open your terminal or command prompt and type in the command node followed by the enter key. This will immediately open the Node.js shell and allow you to start coding.
Executing JavaScript code
Once you have launched the Node.js shell, you can start writing JavaScript code. The shell will immediately start evaluating any code you enter and display the result of that code.
To execute a line of JavaScript code in the Node.js shell, type the code into the prompt and press enter. The shell will then execute the code and display the result.
Here is an example:
“`
> console.log(“Hello, World!”);
Hello, World!
undefined
“`
In this example, we have executed a line of code that prints the string Hello, World! to the console. The Node.js shell then displays the string as output, followed by
undefined since the console.log function does not return any value.
One important thing to note is that the Node.js shell is just a JavaScript environment, so everything you can do in JavaScript, you can do in the Node.js shell. This means you can define variables, create functions, and execute complex code just like you would in a regular JavaScript file.
Exiting interactive mode
Once you are done testing and experimenting with the Node.js shell, you can exit interactive mode by typing the “.exit” command and pressing enter. This will immediately close the Node.js shell and return you to your command prompt or terminal.
Conclusion
Whether you are a beginner or an experienced developer, using the Node.js interactive environment is a great way to get started with Node.js. It allows you to test and experiment with code quickly and easily, without the need to create a separate script.
So, what are you waiting for? Launch the Node.js shell and start exploring the amazing possibilities it has to offer!
This article provided a comprehensive guide on installing and launching Node.js, as well as a detailed guide on using the Node.js interactive environment.
