Here are some key differences between HTML and JavaScript:
HTML is static, meaning content remains unchanged until reloaded, whereas JavaScript is interactive, updating dynamically based on user actions. HTML works with CSS to define the visual layout, while JavaScript works with HTML and CSS to enable interactivity.
Content Manipulation
HTML is a markup language that can't modify content dynamically, it can only organize content into elements like headings, paragraphs, lists, tables, and forms. This means that HTML content remains static unless developers modify it via external means like JavaScript or CSS.
JavaScript, on the other hand, is a programming language that enables developers to manipulate webpage content dynamically. It can modify elements, update text, handle user inputs, and respond to events through the Document Object Model (DOM).
The Document Object Model (DOM) is a tree-like structure that represents a webpage as a collection of elements that JavaScript can access and modify. This allows JavaScript to create dynamic and interactive web pages that can respond to user actions in real-time.
