JSFunctionSpec
to define an array of jspropertyspec, use js_fs, js_fn, js_sym_fn, js_fninfo, js_self_hosted_fn, js_self_hosted_sym_fn, js_sym_fnspec, js_fnspec, and js_fs_end.

JS_DefineFunctions
this array is usually defined as a static global, with each record initialized using js_fs or js_fn.
...(the macro js_fs_end can be used for the last element.) js_definefunctions creates one function for each non-zero element in the array.

JS_InitClass
fs jsfunctionspec * either null or a pointer to the first element of an array of jsfunctionspecs, terminated by js_fs_end.
...(this is the nearest javascript equivalent of public static member variables in c++ or public static fields in java.) static_fs jsfunctionspec * either null or a pointer to the first element of an array of jsfunctionspecs, terminated by js_fs_end.
