It might be almost similar but relatively different in a big way for blocks may appear only in the source adjacent to a method call which means it should be written on the same line as the method’s last parameter and it is not implemented once it is encountered but, Ruby rather remembers the context [...]

As stated in the past post, we aim to simplify further the code we have just created with the following shorter version of the same program. class BookList def [](key) if key.kind_of?(integer) result = @Books[key] else result = @Books.find { |aBooks| key == sBooks.name} end return result end end Further shortening the code we have [...]

We now go through a process which implements the code on the [] method we just showed where we will take a string, searches for the book with the same title. The method would go through the whole table one at a time to get a match as shown with the following: class BookList def [...]

Using the append command/method, we can add an element to the end of the table which in turn returns a reference to the current BookList object.The deleteFirst and deleteLast command allows us to delete the first and last records respectively in the following form/s: For Append: class BookList def append(aBook) @books.push(aBook) self end end For [...]
