What is functional programming in Ruby?
Functional programming in Ruby is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state or mutable data.
Can you give me an example of a functional programming concept in Ruby?
Sure! One common concept is the use of higher-order functions, like map
, which applies a block of code to each element in an array.
How does the map
method work?
The map
method creates a new array containing the results of running the block once for every element in the original array.
Are there any other functional programming features in Ruby?
Yes, Ruby supports features like lambdas, procs, and immutability, which are key aspects of functional programming.
