What is the key feature of Ruby that makes it a dynamic programming language?

One of the key features of Ruby that makes it a dynamic programming language is its dynamic typing system. In Ruby, variables are not bound to a specific data type at the time of declaration. Instead, the data type is determined and assigned dynamically during runtime based on the value assigned to the variable. This dynamic typing feature provides flexibility and allows for more expressive and concise code. Developers can create variables without explicitly declaring their types, which reduces the need for explicit type annotations and simplifies the development process. With dynamic typing, Ruby allows variables to hold different types of values at different points i....
