JavaScript Tutorial

Welcome to the JavaScript tutorial! JavaScript is a high-level, often just-in-time compiled language that conforms to the ECMAScript specification. It is widely used for web development, enabling interactive web pages and web applications.

What is JavaScript?

JavaScript is a scripting language that allows you to manipulate web pages dynamically. It is an essential part of web development, working alongside HTML and CSS to create interactive and dynamic websites.

Features of JavaScript:

Event-Driven: JavaScript allows you to execute code in response to events, such as clicks, mouse movements, or key presses.
Platform Independent: JavaScript runs on all major browsers without the need for additional plugins.
Rich Ecosystem: There is a vast ecosystem of libraries and frameworks available for JavaScript development.

Getting Started

To get started with JavaScript, you need a text editor and a web browser. You can write JavaScript code in a text editor and open the file in a web browser to see the results.

Install a Text Editor

Choose a text editor that you are comfortable with. Some popular options include Visual Studio Code, Sublime Text, and Atom.

Open a Web Browser

Open your preferred web browser. You can use any of the major browsers like Chrome, Firefox, Safari, or Edge.

Your First JavaScript Program

Here's a simple example of a JavaScript program that prints "Hello, World!" to the console:

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

To run this code, open your text editor, paste the code above, and save the file with a .js extension, such as hello.js. Then, open the file in your web browser, and you should see the message "Hello, World!" in the browser's console.
