# Introduction

In this section you will be introduced to a series of concepts related to functional programming. These concepts are usually abstract, but the **Tango** library have concrete implementations with it.

Here you will find the following subsections:

* [Using Pattern Matching](https://github.com/gabrielschade/tango/tree/379cc4a38ae47796971eb875ec66e7dc053a9081/Concepts/Pattern%20Matching.html)
* [Option values](https://github.com/gabrielschade/tango/tree/379cc4a38ae47796971eb875ec66e7dc053a9081/Concepts/Optional%20Values.html)
* [Either values](https://github.com/gabrielschade/tango/tree/379cc4a38ae47796971eb875ec66e7dc053a9081/Concepts/Either%20Values.html)
* [From void to Unit](https://github.com/gabrielschade/tango/tree/379cc4a38ae47796971eb875ec66e7dc053a9081/Concepts/From%20void%20to%20Unit.html)
* [Func and Action](https://github.com/gabrielschade/tango/tree/379cc4a38ae47796971eb875ec66e7dc053a9081/Concepts/Function%20and%20Action.html)
