Ruby is seen as a flexible language, since it allows its users to freely alter its parts.

Essential parts of Ruby can be removed or redefined, at will.

Existing parts can be added upon. Ruby tries not to restrict the coder

Ruby’s block are also seen as a source of great flexibility.

A programmer can attach a closure to any method, describing how that method should act

The closure is called a block and has become one of the most popular features for newcomers to Ruby from other imperative languages like PHP or Visual Basic.

There are many other methods in Ruby which help the developer to write their own block to fill in the details of what that method should do.

Unlike many object-oriented languages, Ruby features single inheritance only, on purpose.

But Ruby knows the concept of modules .

Modules are collections of methods

Classes can mixin a module and receive all its methods for free.

So for developers this is a much clearer way than multiple inheritance, which is complex and can be too restrictive.

Generally Ruby often uses very limited punctuation and usually prefers English keywords, some punctuation is used to decorate Ruby
