Choose a Text Editor or Integrated Development Environment (IDE):
You can start with a simple text editor like Visual Studio Code (VSCode) or a more feature-rich IDE like WebStorm.
Download and install your chosen editor/IDE from their respective websites.
Download and install Node.js from the official website: https://nodejs.org/
Open your text editor/IDE and create a new file with a .js extension. For example, app.js.
Let’s start with a simple “Hello, World!” example.
In your app.js file, type the following code:
Open your terminal or command prompt.
Navigate to the directory where your app.js file is located.
You should see the output: Hello, World!
Create a new HTML file, e.g., index.html, and add the following code:
This code includes your app.js file in the HTML page.
Double-click the index.html file or open it with your preferred web browser.
Open the browser’s developer console (usually by pressing F12 or right-clicking and selecting “Inspect”).
You should see the “Hello, World!” message in the console.
Most modern browsers have built-in developer tools for debugging.
You can set breakpoints, inspect variables, and step through your code to find and fix issues.
In VSCode or your chosen IDE, you can also set breakpoints and debug Node.js applications.
