Is everything in Ruby an object?

Câu trả lời

In Ruby, not everything is an object. While Ruby is known for its pure object-oriented approach where many elements like strings, arrays, and even classes are objects, there are exceptions. Specifically, methods, blocks, and keywords are not objects in Ruby. However, it is important to note that there are Method objects and Proc objects available, which can encapsulate methods and blocks respectively[3]. This distinction is crucial in understanding Ruby's object model and its capabilities.
