Background

In functional programming, you tend to create specialized functions that complete certain tasks. In these cases, programmers rely on abstractions and expect the function to work. However, these practices can lead to chaining multiple functions, resulting in calling many functions, one after the other. To beautify code and make your life easier, use function composition.

Introduction to function composition

Function composition is an approach where the result of one function is passed to the next function, and then to another, until the final function is executed. They can be composed of any number of functions.
