Method: Array#==

Defined in:
array.c

#==(other_array) ⇒ Boolean

Returns whether both:

  • self and other_array are the same size.

  • Their corresponding elements are the same; that is, for each index i in (0...self.size), self[i] == other_array[i].

Examples:

[:foo, 'bar', 2] == [:foo, 'bar', 2]   # => true
[:foo, 'bar', 2] == [:foo, 'bar', 2.0] # => true
[:foo, 'bar', 2] == [:foo, 'bar']      # => false # Different sizes.
[:foo, 'bar', 2] == [:foo, 'bar', 3]   # => false # Different elements.

This method is different from method Array#eql?, which compares elements using Object#eql?.

Returns:

  • (Boolean)
