Pure functions. The ideal in functional programming is what is known as pure functions.A pure function is one whose results are dependent only upon the input parameters, and whose operation ...

In functional programming, a pure function is a function that always produces the same output for the same input and has no side effects. It doesn't modify any external state or rely on mutable data.

Continuing with our programming series, we will talk about Function – much of all that it entails. Understanding functions is important if you want to learn how to code. The same applies to ...

The function changeGPAs() would take in the students’ array. It would then call changeGPA() for each value in the students array, and return the result as a new array. The job of changeGPA() is to ...

Spread the loveIn programming, a function is a set of instructions that perform a specific task. It is a block of code that can be easily reused, making programming more efficient and modular.

Programming languages break down into broad categories. There are imperative languages, which say, “do this, then do that,” specifying a series of steps to accomplish a task. Functional languages, on ...

A category in category theory is a collection of objects and morphisms between them. In programming, typically types act as the objects and functions as morphisms. To be a valid category, three rules ...

Pure functions have several advantages over impure functions. First, they are easier to reason about, since you only need to consider the input and output, not the context or history of the program.
