Is Vanilla JavaScript a front-end or back-end language?
Vanilla JavaScript refers to plain JavaScript without frameworks or libraries, used for both front-end browser development and back-end Node.js server development. In the browser, Vanilla JS handles DOM manipulation, event handling, and async operations via the Fetch API. On the server, Vanilla JS with Node.js powers HTTP services, file operations, and API development. In 2026, Vanilla JS is a viable choice for simple browser scripts and lightweight services where framework overhead is not justified.
