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.

# Binaries
The binary type represents a sequence of bits. A binary literal looks like `<< term,... >>`.
The simplest term is just a number from `0` to `255`. The numbers are stored as successive bytes in the binary.

```elixir
iex> b = << 1, 2, 3 >> 
<<1, 2, 3>>

iex> byte_size b
3

iex> bit_size b 
24
```
We can specify modifiers to set any term’s size (in bits). This is useful when working with binary formats such as media files and network packets.

```elixir
iex> b = << 1::size(2), 1::size(3) >>  # 01 001
<<9::size(5)>>     # = 9 (base 10)

iex> byte_size b  
1

iex> bit_size b 
5
```
We can store integers, floats, and other binaries in binaries.
```elixir
iex> int = << 1 >>
<<1>>

iex> float = << 2.5 :: float >>
<<64, 4, 0, 0, 0, 0, 0, 0>>

iex> mix = << int :: binary, float :: binary >> 
<<1, 64, 4, 0, 0, 0, 0, 0, 0>>
```
