JSAPI Cookbook
to query whether a value has a particular type, use a correspondingly named member testing function: // javascript var v = computesomevalue(); var isstring = typeof v === "string"; var isnumber = typeof v === "number"; var isnull = v === null; var isboolean = typeof v === "boolean"; var isobject = typeof v === "object" && v !== null; /* jsapi */ js::rootedvalue v(cx, computesomevalue()); bool isstring = v.isstring(); bool isnumber = v.isnumber(); bool isint32 = v.isint32(); // note: internal representation, not numeric value bool isnull = v.isnull(); bool isboolean = v.isboolean(); bool isobject = v.isobject(); // note: not broken like typeof === ...
...ull; v = undefined; v = false; /* jsapi */ js::rootedvalue v(cx); js::rootedstring somestring(cx, ...); v.setint32(0); // or: v = js::int32value(0); v.setdouble(0.5); // or: v = js::doublevalue(0.5); v.setstring(somestring); // or: v = js::stringvalue(somestring); v.setnull(); // or: v = js::nullvalue(); v.setundefined(); // or: v = js::undefinedvalue(); v.setboolean(false); // or: v = js::booleanvalue(false); finding the global object many of these recipes require finding the current global object first.
... in cases where it is certain that y is an object (that is, not a boolean, number, string, null, or undefined), this is fairly straightforward.

JSAPI User Guide
a js::value can be a number, a string, a boolean value, a reference to an object (like an object, array, date, or function), or one of the special values null or undefined.
