Setting up the Development Environment

To begin your journey into JavaScript development, you need to set up your development environment. This involves installing and configuring the necessary tools that will enable you to write and run JavaScript code on your machine.

Installing Node.js

Node.js is a JavaScript runtime environment that allows you to run JavaScript on the server-side. It provides a powerful set of tools and libraries for building web applications. To get started, follow these steps:

1. Visit the official Node.js website at nodejs.org and download the latest version of Node.js for your operating system.

2. Run the Node.js installer and follow the installation instructions.

3. Once the installation is complete, open a terminal or command prompt and type the following command to verify that Node.js was installed successfully:

1node -v

If the installation was successful, the command will display the installed version of Node.js.

Choosing a Code Editor

A code editor is a tool that allows you to write and edit your code. There are several popular code editors available for JavaScript development. Here are a few options:

• Visual Studio Code
• Sublime Text
• Atom

Choose the code editor that best fits your needs and preferences, and install it on your machine.

Creating a JavaScript File

Once you have installed a code editor, you can create a new JavaScript file. This file will be used to write your JavaScript code. Here's how you can create a new JavaScript file:

1. Open your code editor and create a new file.

2. Save the file with a .js extension, for example, script.js.

Now you're all set to start writing and running JavaScript code on your machine!

To get started, let's write a simple JavaScript program that will display 'Hello, World!' in the console. Copy the following code into your JavaScript file:

1console.log('Hello, World!');

Save the file and open a terminal or command prompt. Navigate to the directory where you saved the JavaScript file, and run the following command to execute the program:

1node script.js

If everything is set up correctly, you will see 'Hello, World!' printed in the console.
