Instance Method Details

- (Object?) find! { ... } Also known as: find_and_map

Finds the first element for which the block returns a true value and returns the value of the block

It works like Enumerable#find, but, instead of returning the element for which the block returned a true value, it returns the value returned by the block. if the block returns nil or false for all elements

Examples:

Using find!

[1, 2, 3, 4].find!{|i| 2*i if i > 2}
=> 6 #(3*2)

Yields:

  • obj

Returns:

  • (Object, nil) —

    the first non-false value returned by the block or nil
