Server-side JavaScript (SSJS) refers to JavaScript that runs on server-side. This term was coined because the language was originally limited to just client-side, i.e. client-side JavaScript (CSJS)..

The first implementation of SSJS was Netscape's LiveWire, included in their Enterprise Server 2.0 product, released in 1996.
