FAQs on Ruby Programming Tutorial-23-Freeze Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming

1. What is back-end programming in Ruby?
Ans. Back-end programming in Ruby refers to the process of developing and designing the server-side logic of a web application using the Ruby programming language. It involves handling data storage, database interactions, server management, and other backend operations.
2. How can I freeze a Ruby object?
Ans. In Ruby, you can freeze an object by using the `freeze` method. This method prevents any further modifications to the object, making it immutable. Once an object is frozen, any attempt to modify its attributes or call methods that modify it will raise an error.
3. What is the purpose of freezing a back-end program in Ruby?
Ans. Freezing a back-end program in Ruby ensures that the code remains unchanged and secure. By freezing the program, you prevent any accidental or unauthorized modifications, making it easier to maintain and preventing potential bugs or vulnerabilities.
4. Can I unfreeze a frozen object in Ruby?
Ans. No, once an object is frozen in Ruby, it cannot be unfrozen. The `freeze` method permanently freezes the object, making it immutable. If you need to modify the object, you will need to create a new instance and copy the desired attributes.
5. How can I check if an object is frozen in Ruby?
Ans. You can check if an object is frozen in Ruby by using the `frozen?` method. It returns `true` if the object is frozen and `false` if it is not. This can be useful to determine the state of an object before attempting any modifications.
