In Elixir, it is common to loop over an Enumerable, often filtering out some results and mapping values into another list. Comprehensions are syntactic sugar for such constructs: they group those common tasks into the `for` special form.

For example, we can map a list of integers into their squared values:

In this tutorial, we are going to teach you about Elixir fundamentals - the language syntax, how to define modules, how to manipulate the characteristics of common data structures, and more. This chapter will focus on ensuring that Elixir is installed and that you can successfully run Elixir's Interactive Shell, called IEx.

So far we haven't discussed any associative data structures, i.e. data structures that are able to associate a certain value (or multiple values) to a key. Different languages call these different names like dictionaries, hashes, associative arrays, etc.

In Elixir, we have two main associative data structures: keyword lists and maps. It's time to learn more about them!

[Domain-specific languages (DSL)](https://en.wikipedia.org/wiki/Domain-specific_language) allow developers to tailor their application to a particular domain. You don't need macros in order to have a DSL: every data structure and every function you define in your module is part of your Domain-specific language.

## Foreword

1210
Even though Elixir attempts its best to provide a safe environment for macros, the major responsibility of writing clean code with macros falls on developers. Macros are harder to write than ordinary Elixir functions and it's considered to be bad style to use them when they're not necessary. So write macros responsibly.

This guide aims to introduce the meta-programming techniques available in Elixir. The ability to represent an Elixir program by its own data structures is at the heart of meta-programming. This chapter starts by exploring those structures and the associated `quote` and `unquote` constructs, so we can take a look at macros in the next chapter and finally build our own domain specific language.

In this chapter, we will learn how to keep and share state between multiple entities. If you have previous programming experience, you may think of globally shared variables, but the model we will learn here is quite different. The next chapters will generalize the concepts introduced here.
