- Add separate APIs for creating different kinds of numbers, because creating a V8 number value from an integer is faster than creating one from a double. - When getting number values, avoid getting the current context because the context will not actually be used and is expensive to obtain. - When creating values, don't use v8::TryCatch (NAPI_PREAMBLE), because these functions have no possibility of executing JS code.
