The history of â€œtypeof nullâ€
Update 2013-11-05: I take a look at the C code of typeof to better explain why typeof null results in 'object'. In JavaScript, typeof null is 'object', which incorrectly suggests that null is an object (it isnâ€™t, itâ€™s a primitive value, consult my blog post on categorizing values for details). This is a bug and one that unfortunately canâ€™t be fixed, because it would break existing code. Letâ€™s expl

harmony:typeof_null [ES Wiki]
under the Harmony version, but the Result would rem ain â€œobjectâ€ under the default version. Version details TBD. Some JS on the web carefully tests both typeof x === â€œobjectâ€ && x === null or equivalent in order to distinguish null from an object reference. Other code is less careful. The ongoing burden on JS authors, maintainers, teachers, and learners is a small but (over time) significant cost.
