JavaScript is the most powerful and versatile web programming language. It is used for making the websites interactive. JavaScript helps us add features like animations, interactive forms and dynamic content to web pages.JavaScript is very easy to implement because it is integrated with HTML. It is open and cross-platform.

Features of JavaScript:

Client-side scripting: JavaScript is mainly used in web browsers to manipulate HTML and CSS, allowing developers to create rich user interfaces and dynamic content.

Cross-platform: It works across various platforms, operating systems, and browsers.

Lightweight: Designed for handling tasks within the browser, it's not memory-intensive or resource-heavy.

First-class functions: Functions in JavaScript are treated like any other variable, which allows functions to be passed as arguments, returned from other functions, and assigned to variables.

Example

<!DOCTYPE html>

<html>

<head>

<title>JS Basic Example</title>

</head>

<body>

<h1>My First Web Page</h1>

document.getElementById("demo").innerHTML = 5 + 6;

</script>

</body>

</html>
