“JavaScript Tutorial for Beginners: What is JavaScript?

Introduction to JavaScript

1).JavaScript is a dynamic programming language primarily used for web development.

2). It adds interactive elements, animations, and dynamic behavior to web pages.

3).JavaScript can be executed on the client-side within a web browser, making it ideal for creating responsive user interfaces.

Getting Started:

1). All you need to start coding in JavaScript is a simple text editor like Notepad or a more advanced integrated development environment (IDE) like Visual Studio Code.

2). JavaScript code can be embedded directly within HTML documents using the <script> tag or saved in separate .js files and linked to HTML files.

3.To execute JavaScript code, open your HTML file in a web browser, and the browser will interpret and run the JavaScript code.

    <h1>Hello, World!</h1>
        alert('Welcome to JavaScript!');
