include
include(object) -> Boolean
Determines whether a given object is in the Enumerable
or not, based on the ==
comparison operator. Aliased as member
.
Note this is not strict equality (===
, comparing both value and type), but
equivalence (just value, with implicit conversions).
If you need to check whether there is an element matching a given predicate,
use any
instead.
Examples
$R(1,15).include(10)
// -> true
['hello', 'world'].include('HELLO')
// -> false
[1, 2, '3', '4', '5'].include(3)
// -> true (== ignores actual type)
