Welcome to the world of JavaScript! JavaScript is an essential programming language for web development and is widely used by developers around the world. It is used to create interactive websites and applications and is essential for web development. With the increasing demand for web development, the need for JavaScript knowledge has also grown. As such, developers need to understand the basics of JavaScript. This blog provides an introduction to JavaScript in Malayalam, making it easier for developers to learn and understand the language in your mother tongue. We will explain the basics of the language, show you how to write code and discuss the different types of projects you can create with it. With our assistance, you will gain the necessary knowledge to start coding in JavaScript and create amazing web applications. So, let’s get started!
What is JavaScript?
JavaScript, abbreviated as JS, is a programming language that, together with HTML and CSS, is one of the foundational technologies of the World Wide Web. It is a scripting language that allows you to generate dynamically updated data, manipulate multimedia, animate graphics, and perform other tasks.
JavaScript is an ECMAScript-compliant high-level, typically just-in-time compiled language. It supports dynamic typing, prototype-based object-oriented programming, and first-class functions. It helps event-driven, functional, and imperative programming approaches and is a multi-paradigm. It includes APIs for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM). The ECMAScript standard does not include input/output (I/O) capabilities such as networking, storage, or graphics. In practice, JavaScript APIs for I/O are provided by the web browser or another runtime system.

How to Run JavaScript?
JavaScript, as a scripting language, cannot run on its own. In actuality, the browser is in charge of executing JavaScript code. When a user requests an HTML page that contains JavaScript, the script is transmitted to the browser, and the browser is responsible for executing it. The key advantage of JavaScript is that it is supported by all modern web browsers. As a result, you don’t have to be concerned about whether your site visitor is using Internet Explorer, Google Chrome, Firefox, or another browser. JavaScript will be available. Furthermore, JavaScript is compatible with every operating system, including Windows, Linux, and Mac. Thus, JavaScript addresses the fundamental drawbacks of VBScript (now outdated), which is limited to only Internet Explorer and Windows.
Needed Tools
To begin, you’ll need a text editor to write your code and a browser to view the web pages you create. You can use any text editor you prefer, such as Notepad++, Visual Studio Code, Sublime Text, Atom, or any other text editor you are familiar with. Any online browser, including Google Chrome, Firefox, Microsoft Edge, and Internet Explorer, can be used.

A Basic JavaScript Programme
If you want to preserve your JavaScript code within the HTML document, you should put it all within script> tags (script> and /script>). This allows your browser to distinguish between your JavaScript code and the rest of the code. Because there are alternative client-side scripting languages (for example, VBScript), it is strongly advised that you identify the scripting language you intend to utilize. You must include the type attribute within the script> tag and set its value to text/javascript, as seen below:
<script type=”text/javascript”>
An Example:
<html>
<head>
<title>My First JavaScript code!!!</title>
<script type=”text/javascript”>
alert(“Hello World!”);
</script>
</head>
<body>
</body>
</html>
