(namespace x)


Returns the namespace string of a possibly namespace-qualified keyword or symbol.

Returns nil if not present.


With namespaces:

(namespace :foo/bar)
;;=> "foo"

(namespace 'foo/bar)
;;=> "foo"

Without namespaces:

(namespace :foo)
;;=> nil

(namespace 'foo)
;;=> nil

Strings have no concept of a namespace:

(name "foo/bar")
;;=> nil
