Functional Programming

Object-Oriented Programming (OOP) provides us with a way of thinking about objects, thus expressing the real world in terms of classes and their relationships. Functional programming is a completely different programming paradigm as it allows us to concentrate on the functional structure rather than the physical structure of code. Learning and using functional programming are useful in two ways. First, it is a new paradigm that forces you to think very differently. Solving problems requires having flexible thinking. People that are attached to a single paradigm tend to provide similar solutions to any problem, while most elegant solutions require a wider approach. Mastering functional programming provides developers with a new skill that helps them provide even better solutions to problems. Secondly, using functional programming reduces the number of bugs...
