include :: Enumerable

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)
