The programming language often referred to as the "language of the web" is JavaScript. JavaScript is a high-level, dynamic scripting language primarily used to create interactive and dynamic content on websites. It enables developers to implement features like animations, form validations, and asynchronous fetching of data from servers. JavaScript works alongside HTML and CSS to build responsive user interfaces and enhance the overall user experience. Over the years, it has expanded beyond web browsers to include server-side programming with platforms like Node.js, making it a versatile language in the tech landscape.
