The difference between JavaScript and HTML

1. The essential difference

HTML is A markup language, JavaScript is a scripting language.

HTML, Hyper Text Markup Language, is an application under the standard universal markup language. HTML is not a programming language, but a markup language, which is necessary for web page production.

JavaScript (often abbreviated to JS) is a high-level, interpreted programming language. JavaScript provides syntax to manipulate text, arrays, dates, and regular expressions. It does not support I/O, such as network, storage, and graphics, but these can be supported by its host environment.

2. Usage difference

HTML provides static content on the web page. JavaScript adds dynamic functionality to static web pages.

JavaScript can be embedded in HTML, but HTML cannot be embedded in JavaScript.

3. Standardization difference

HTML is based on W3C and WHATWG standards, and JavaScript is based on ECMA standards.

4. Compatibility difference

HTML is cross-browser compatible, which means it is compatible with all versions of all web browsers, including modern browsers. All browsers, whether old or new, handle unrecognized elements as inline elements by default, which makes it easy for older web browsers to handle unknown HTML elements.

On the other hand, JavaScript lacks cross-browser compatibility, which makes some functions incompatible with certain browsers.
