描述

-

The value null is written with a literal, null (it's not an identifer for a property of the global object like {{jsxref("Global_Objects/undefined","undefined")}} can be). In APIs, null is often retrieved in place where an object can be expected but no object is relevant. When checking for null or undefined beware of the differences between equality (==) and identity (===) operators (type-conversion is performed with the former).
