Learn the basics of Elixir, along with advanced concepts such as OTP servers and multiple processes.

Become an Elixir Programmer

In this module, we’ll learn everything we need to know to start working with Elixir, including processing collections, using multiple tools, and working with OTP servers. Programmers usually learn by writing code, and that’s exactly how this module will also work. We'll practice a lot of coding examples that will help us get a strong grip on Elixir.

# Introduction

Sets are implemented using the module `MapSet`. Here are the different functionalities that we can perform with a set. Let's take a look at short commands:

```elixir
iex> set1 = 1..5 |> Enum.into(MapSet.new) 
#MapSet<[1, 2, 3, 4, 5]>
```
```elixir
iex> set2 = 3..8 |> Enum.into(MapSet.new) 
#MapSet<[3, 4, 5, 6, 7, 8]>
```
# Functionalities

In the above commands, we’re making two sets using the `new` method of `MapSet` module. These sets are stored in `set1` and `set2`, respectively. Below are further simple functionalities of sets:
```elixir
iex> MapSet.member? set1, 3
true
```
```elixir
iex> MapSet.union set1, set2 
#MapSet<[1, 2, 3, 4, 5, 6, 7, 8]> 
```
```elixir
iex> MapSet.difference set1, set2 
#MapSet<[1, 2]>
```
```elixir
iex> MapSet.difference set2, set1 
#MapSet<[6, 7, 8]>
```
```elixir
iex> MapSet.intersection set2, set1 
#MapSet<[3, 4, 5]>
```
Run and practice these simple codes in the given terminal.
