Function mozjs::jsapi::JS_InitStandardClasses

pub unsafe extern "C" fn JS_InitStandardClasses(
    cx: *mut JSContext, 
    obj: Handle<*mut JSObject>
) -> bool

Initialize standard JS class constructors, prototypes, and any top-level functions and constants associated with the standard classes (e.g. isNaN for Number).

NB: This sets cx's global object to obj if it was null.
