Java Script Complete Notes

Summary:

JavaScript is a high-level, interpreted programming language widely used to create dynamic and interactive web applications. It is one of the core technologies of the World Wide Web and runs on virtually every modern web browser. JavaScript allows developers to add functionality, interactivity, and responsiveness to web pages, making them more engaging and user-friendly.

With JavaScript, developers can manipulate and modify the content and behaviour of web pages in real-time. It provides many features and capabilities, including event handling, form validation, animations, and dynamic content updates. JavaScript can also interact with other web technologies, such as HTML and CSS, enabling seamless integration and enhancing the overall user experience.
