In software, Functors can be viewed as a util class that allows us to perform a mapping operation over values wrapped in some context. It can also be viewed as an interface proving a certain ability, namely the ability to transform the state of an object.
In category theory, an Applicative, also known as an Applicative Functor, is a concept that generalizes a Functor by allowing for operations not just on the values inside a context but also on functions within a context.
