JS4mIRC is the minimalist's interpreter language binding. It gives the scripter the ability to load Javascript code as well as embed it directly into mIRC script files. It uses the same JavaScript engine used by Firefox, written in C, and is not only fast but very lightweight-- the entire JS4mIRC interpreter and binding package is less than 1MB. The language may not be fully loaded like Python, Ruby or Tcl, but it's great for fast XML or text processing. This makes it great when you want the speed boost of a bytecode compiled language without the extra memory footprint of a full standard library or installed dependencies.
