Javascript introduction and setup

Created By: chatGPT

JavaScript is a versatile programming language primarily used for web development. It allows developers to create interactive and dynamic content on web pages. Here’s how you can set up your development environment and get started with JavaScript.To begin, you need a text editor. Options include Visual Studio Code, Sublime Text, or Atom. For this tutorial, we'll use Visual Studio Code, which is widely popular and feature-rich.Once you have installed Visual Studio Code, you can create a new JavaScript file. For example, create a file named script.js. In this file, you'll write your JavaScript code.

To run your JavaScript code in a web browser, you need to create an HTML file to link your JavaScript file. Create a new file named index.html. Add the following structure to this file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My JavaScript Page</title>
</head>
<body>
    <script src="script.js"></script>
</body>
</html>

Now, add some simple code to your script.js file. Let’s start with a basic program that displays a greeting on the console:

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

You can open your index.html file in a web browser, like Google Chrome or Firefox. Right-click the page and select Inspect or press F12 to open the Developer Tools. Navigate to the Console tab to see your greeting message.Congratulations! You've just set up your JavaScript environment and run your first JavaScript program. From here, you can explore more advanced JavaScript features, such as variables, functions, and event handling to create more interactive web applications.
