Explain the features of ruby on rails.

 Some of the features of ruby on rails are listed below-

• Meta-programming: code generation is used but for heavy lifting, it uses meta-programming.
• Active record: objects are saved to the database through this framework. It identifies the columns in a schema and binds them to your domain object.
• Scaffolding: it means it has the ability of creating temporary code automatically.
• Convention over configuration: much configuration is not needed if the naming convention is followed.
• Three environments: testing, development, and production are the three default environments in this framework.
• Built-in testing: test cases are used in this for writing and executing the codes.
