Hi bill

JavaScript itself is not inherently a backend language because it was originally created to run in the browser for client-side scripting handling things like DOM manipulation, user interaction, and dynamic UI updates.

However, with the introduction of Node.js (which runs JavaScript on the server using the V8 engine), JavaScript can now be used for backend development. So the distinction is historical rather than technical — it’s not that JavaScript cannot be backend, but that it wasn’t originally designed for it.

In short:

  • Originally: JavaScript → frontend only (browser).
  • Now: JavaScript → frontend + backend (via Node.js, Deno, Bun, etc.).
