SpiderMonkey

SpiderMonkey is the code name for the first ever JavaScript engine, written by Brendan Eich at Netscape Communications, later released as open source and now maintained by the Mozilla Foundation.

SpiderMonkey is written in C and contains a compiler, interpreter, decompiler, garbage collector, and standard classes. It does not itself provide host environments such as Document Object Model (DOM).

SpiderMonkey and its sister engine Rhino have implemented support for the ECMAScript for XML (E4X) standard.
